Sitting at my old demo group’s 30th anniversary party (which I mentioned in this blog post), I had no inkling that we were in fact reviving a tradition. I’m happy to say that since that first reunion, we’ve been meeting on a fairly regular basis to compare notes, play with our machines and discuss all things Amiga. We’re now a mixed bunch consisting of retro hardware collectors, next-gen enthusiasts (yes, me) and occasional emulation users, but the meetings are always great fun!

Although the hotel that hosted our anniversary get-together was great, we felt that for future meetings we had better look for a less formal venue. And it didn’t take much brainstorming to come up with one. High on our mental list was a cabin at the shore of the Vranov Lake, a place near the border with Austria where we last stayed in mid-1990s. At that time, the Czech Amiga demoscene was having its finest moments, and the poor cabin saw the leading scene groups coming down for annual summer parties (which we now like to present as legendary). “Is the cabin still available for hiring?” we asked Lagya of the Guru Team, who used to organize the parties. He promised to find out with the owner, and in a few days the answer came that we got the green light. This was last September, and our very laid-back revival weekend at the cabin left no one doubting that we’d hit the lakeside again this year.

I took a day off work so that I could arrive on Thursday evening, because weekends in the countryside always feel too short. Erm… okay, I’ll own up: the real reason was that Human Factor (our group’s graphic artist and co-founder) offered to drive me in his Tesla. As a non-driver I don’t care about cars very much, but I must admit that the Model S is a slick and comfortable vehicle – and more importantly, the rides with Human Factor are always good value because of the talks we have. The two of us really go way back! In the Amiga days we tried to make a name in the game development business, and like many other sceners dreamed of turning our creative skills into a paid job. But while I chickened out after a few unsuccessful projects (and instead pursued a safe, salaried career), Human Factor didn’t give up trying, and after a few bumpy years his company Krieg Games started making some serious bucks on mobile platforms. I’m really happy for him – especially as he never hesitates to acknowledge that the Amiga played a key role in his professional upbringing.

Upon arriving at the lake, I realized to my horror that in the hustle of packing (combined with the darkness of the storage room) I had grabbed the wrong monitor stand, which wouldn’t hold my 24″ screen. The ugly DIY that I performed to make it fit would surely cause some raised eyebrows at Hewlett-Packard, but at least the situation was saved and I could finally hook up my X5000. The Classic section was represented by two MiSTer FPGA computers – a new thing at the party but one that quickly won us over. The sheer number of systems this little box can emulate is very impressive, and the level of Amiga compatibility is so high that nobody seemed to miss the two genuine A500s we had there last year. At one point I was seriously considering putting the MiSTer on my Christmas wish list, but second thoughts crept in as I pictured the look on my dear wife’s face. You know, the look that says “Is this power brick really a computer?!”

None of my pals in our group owns a next-generation Amiga system, and I’ve never tried to coax them into buying one. They haven’t experienced the turbulent excitement of Amiga’s PowerPC transition, so they might not see a point in getting a toy to which – unlike to the Classic Amiga – they have no emotional attachment. Still, I always like to take the opportunity to demonstrate OS4 and the latest developments on the platform. One reason is that when my X5000 boots up and shows the Workbench screen, people often tend to regard it as little more than a prettied-up, high-resolution version of AmigaOS running on PowerPC. It’s good to show them that despite its troubled history and uneven development, OS4 brings more than just eye candy. So at last year’s Vranov party I previewed the Emotion media player with hardware-accelerated video playback, put the finishing touches to my Mindsurfin’ demo tune in the OS4 version of MilkyTracker, and played some games that had recently been ported to the platform thanks to the new 3D enhancements.

This year I didn’t have any heavy-hitting stuff to surprise with, so my system got less focus than it normally would (also thanks to the heavy competition from the two MiSTer machines). But it was heard all right, for during meal times and talks I streamed various online radios with the help of George Sokianos’ new tuner application MediaVault. The SID Station, a chip music-oriented radio based in Holland, became an instant favourite, so there was a lot of bleeping in the room. The incredible works of Matt Gray, Rob Hubbard or Chris Huelsbeck cannot hope for much airplay at home when your wife’s around, but among computer geeks with 8-bit roots, the music always reaches the right ears.

Anyway, back to MediaVault. It really is one of those under-appreciated little programs that spice up your computing life – and I’m very proud to have contributed a small bit of code to it in its early stages. MediaVault is also one of the things I’ll want to show next time somebody asks, “So what can your glorious OS4 machine do that my Classic Amiga can’t?” George has recently updated his freeware program to cover podcast support, which brings a whole new level of fun and makes MediaVault a perfect solution for your online listening. He has also set up a page on Ko-fi.com, a Patreon-like website where he frequently posts news and development progress updates. We all know that talented AmigaOS4 programmers don’t grow on trees, so why not buy George a nice cup of coffee to support his efforts and show your appreciation? Hell yeah, let’s turn him into a caffeine addict!

Oh, the smell of fresh brew, the smell of morning! I’m an early riser, which gave me about two hours of peace and quiet before the other guys crawled out of their beds. I made good use of this solitary time (and the coffee) to further work on my Rave audio editor, specifically, on the new Process menu, which is shaping up very nicely. At the cabin I was able to add a Fade plugin, which at this point is still very basic, but as it sits on top of Rave’s object-oriented plugin framework, new functionality can easily be added without touching the main program code. My very short-term goal is to add support for logarithmic fading. Essential in professional audio, this feature is in fact a rare find in the Amiga world. Now that I think of it, of all Amiga sound editors I’ve ever used, Stefan Kost’s SoundFX is the only one that can do logarithmic fades – but like everything else in SoundFX, they’re rather complicated to set up there. I’m sure AmigaOS4 composers and sound designers will find them a welcome addition once my Fade plugin gets updated. Other Process menu functions I’ve recently finished include audio channel swapping and conversion, the latter featuring 64-bit floating-point precision mixing for stereo-to-mono conversions.

But the morning time I spent tickling the Rave code was just a nice little extra, a few private hours in which I deliberately allowed work to prevail over fun. There were many great moments at the party – and not just because we had beer on tap and you could self-service yourself to oblivion. Or because you didn’t need to feel awkward watching quirky demos you made quarter a century ago. Thanks to the emulation capabilities of the MiSTer, I was able to correct some of my Amiga-centric views of what other historical computer platforms had to offer, which was an illuminating experience. With quite some trepidation I watched Lagya’s efforts to bring a dead A500 back to life, and I felt a lot of relief that my X5000 saves me from this kind of hardware voodoo; an illuminating experience again. I made a lasting impression on my mates by cooking my trademark goulash, which some of them had the opportunity to see one more time after a bumpy car ride; this experience was not illuminating at all.

But the high-point of the party was our Saturday afternoon visit to the Terra Technica Time Travel Museum in Hatě. I hadn’t heard of the place or visited a similar one before, which added to the power of my experience and turned our trip into an unheralded gem of the weekend. Located just a few kilometers from the Austrian border (and owned by an Austrian guy called Ronnie Seunig), the museum presents itself as “the world’s largest museum of jukeboxes and pinball machines”. Such a description would leave me perfectly cold if, in fact, the place weren’t much more than just that. While the jukebox and the pinball halls were cool with their flashy, deliberately overdone American feel, we preferred to spent more time in the Pixelworld. This video games section of the museum had all the retro computers we love, plus over a dozen machines we had never seen in real life. There were several Amigas including two rare A500 models from Commodore Germany’s 1989 “New Art Limited Edition”, featuring trendy cases designed by the late Stefanie Tücking. I bought my first Amiga in Germany, and I remember I almost went for the ball design A500 because the computer shop was eager to drum up the sales of the Limited Edition, but after some internal struggle I bought the regular one. Silly me. If only my visual taste had been less conservative: I could have a collector’s item now!

When it comes to video games, I must not forget a battery of arcade cabinets they had in a separate hall. Some of these were very old, predating the late 1970s/early 80s arcade game boom, and you simply had to marvel at the resourcefulness of the people who were able to design such wonderful machines through purely electro-mechanical means. Many (if not all, I didn’t check) cabinets were token-operated and playable, just like the pinballs in the other hall. How could we possibly pass up on such an opportunity to relive a bit of our childhood days? I can tell you that a lot of hard-earned cash fell into the token dispenser before we moved on to the last (and newest) section of the museum. The Sound & Vision room, while much lower on the hands-on factor compared to the games hall, was a great place to round off our visit. As the name suggests, this section is dedicated to the history of audio-visual technology. And as if the museum owner thought we hadn’t seen enough interesting gadgets, we found ourselves surrounded by a plethora of historical devices, tools and media, from Edison’s phonograph through shellac discs to early digital recorders. You bet that my audiophile heart bounced with joy!

And then it was Sunday and it was time to put our computers back into their transport boxes, finish the keg, and wrap the party up. Interestingly enough, although we extended our lakeside weekend by one day this year, we were still in the mood for more. Must be some kind of Amiga paradox because this is a feeling I get from almost any Amiga-related event I attend. Another paradox is that I needed almost two months to cover our four-day party, but this is because family matters got in the way unfortunately. I nevertheless hope you’ve enjoyed this belated report as much as we enjoyed our geeky get-together. There’s every indication that it will turn into an annual fixture, so Amigas on the lake are there to stay!

Cieszyn is a quiet border town in Silesia, a historical region that now spans parts of Poland, Germany and the Czech Republic. It is in fact two towns, for fate and politics had it that after World War I and the collapse of the Austro-Hungarian Empire, Cieszyn got divided between Poland and the newly formed country of Czechoslovakia. It wasn’t a very fair split and it’s quite understandable why: with the majority of the local population being Polish, the larger part of the town including the nice historic centre went to Poland, while Czechoslovakia acquired the industrial suburbs in the west.

I remember that at the end of the 1980s, Czech Cieszyn was a run-down place where apathy and despair could be sold in quantity. Grey suburban ugliness shook hands with the communist town-planning butchery, and the ubiquitous feeling of decline was augmented by the grim border guards who, armed to the teeth, patrolled the two bridges separating the town from its Polish sibling. Far off the sightseeing map, the place gave you little reason to come for a visit. Yet I found myself travelling to Czech Cieszyn on an almost monthly basis, and so did many home-computing fans from my area. There was one particular reason why we would happily suffer two hours on a slow train and two hours back – and it certainly wasn’t the snack in the salmonella-infested railway station bistro. The reason was that the bookshops in Czech Cieszyn sold Polish books and magazines.

Now, that probably needs some explanation. At that time, Czechoslovakia was ruled by an authoritarian communist gerontocracy that neither welcomed nor understood modern technology. While in the West the home-computer revolution was in full swing, Czechoslovakia literally sneaked into the new era along the sidelines, thanks to enthusiastic individuals and local communities that found ways, often illegal, to fill in for the non-existent computer market. Surprisingly enough, obtaining hardware wasn’t the biggest problem (although the Iron Curtain was still firmly in place); in fact, by the end of the decade many Czech households owned a Sinclair, an Atari or a Commodore. But information was a precious commodity. The country’s only off-the-shelf magazine devoted to computer technology, Elektronika, largely focused on industrial applications in the Soviet Bloc, and provided little material on home computers. As a teenager with a shiny C64 on your desk, you really didn’t want to read about a bulky mainframe from Bulgaria.

Things were very different in Poland, where computerization was taken more seriously. While also ruled by communists, the country actually had adopted a nationwide computer literacy programme, which went under the official slogan “The Game for Tomorrow.” The Polish government believed that encouraging young people to use computers productively would bring, at a later point, highly skilled workforce that would make an impact on the country’s ailing economy. Among the results of the official policy were two computer magazines that made us Czechs green with envy: Bajtek (which was mainly home-computer oriented) and Komputer (which focused on users from the professional sphere). Compared to our puny Elektronika, both magazines contained far less ideological fluff, and happily covered the latest technological developments in the West. And as a Slavic language, Polish represented a much lower barrier than the German we found in magazines occasionally smuggled from the neighbouring Austria or West Germany. So Bajtek and Komputer provided a good reason to hop on the train and take the lengthy Saturday trip to Czech Cieszyn. The refreshing read made the journey well worth it.

I know that history makes a point of repeating itself, but I’m still finding it hard to believe that – more than thirty years later – I’ve bought a Polish computer magazine again. Why did I bother, now that I can choose from about half a dozen different titles in my native language? Well, this particular mag has one great thing about it: it’s an active, Amiga-oriented print magazine that focuses on the next-generation branch of the platform. Which came as a surprise because for a long time the post-Commodore systems had, at best, shared pages with the classic Amiga in the remaining few magazines such as Amiga Future. This suggested that things had never been peachy enough in the next-gen quarters to justify a dedicated mag. Well, that’s what I thought before I heard of Amiga NG.

Four years ago in Poland they decided to take the plunge and start a magazine to cover the three NG flavours, that is, AmigaOS4, MorphOS and AROS. More importantly (because starting a mag is easy), they were really serious about it. The brainchild of Adam Mierzwa went from a simple PDF-only pilot publication to a full-colour 64-page printed magazine that, at one point, became a regular quarterly and earlier this year made it to issue #10. (This is the part where you say wow!) The efforts of editor-in-chief Mierzwa and his small team have been supported by the Polish publisher Adam Zalepa, whom you may also know as a prolific author of Amiga-themed books and user manuals. Initially unconvinced, Zalepa gradually warmed to the idea of a new magazine, and Amiga NG became part of the impressive range of computer mags published by Zalepa’s company Bitronic. And although I doubt it brings the publisher any profit (considering the low print run, which doesn’t exceed 100 copies), from the buyer’s point of view Amiga NG is certainly not a let-down.

In your hands, the magazine feels unusually heavy with all of its pages printed on thick glossy paper. Very thick in fact – the paper weight surely exceeds that of Amiga Future or Amiga Addict. One cannot help asking if such luxury material is really necessary for a hobby mag, and whether a bit of money could have been saved here to spend it on something else. For example, on page design and typesetting, which is a little crude and basic in Amiga NG. Because quite predictably, the project cannot afford to employ a regular graphic designer, leaving the chief editor responsible for graphic chores on top of his editorial, writing and organizing duties. Someone really ought to come and take the load off the back of that busy Mr. Mierzwa!

As for the magazine content, Amiga NG brings the usual: news, hardware and software reviews, tutorials, reports, interviews, and of course the occasional ad. The 64-page format is rather generous and provides plenty of room for screenshots; it also allows the interviews to go into greater depth. Indeed, I’ve found it is the interview section that is my favourite. The magazine team makes good use of their podcasting experience, so the interviews are well-conducted and bring a lot of interesting information, often spanning several pages. What I especially like is that zeal and optimism do not choke the critical mind. Instead of painting a rosy picture, the mag is often very blunt about the various problems that plague the next-gen Amiga world. I appreciate this realistic mindset, which I think is more beneficial to the platform than self-delusion.

All right, so shall we all now start learning Polish to be able to read Amiga NG? Is that what I’m trying to say here?

No, of course not: the lesson mentioned in the title of this article is purely metaphorical, and has nothing to do with language learning. The educational point is in something else. I’m writing this text because I realize that, for the second time in my life, my Polish neighbours have shown me that a can-do attitude is the perfect recipe for bad times. I can see that whether your computing fun is spoilt by the communist grip or by the frustrating legal mess that is currently ruining the AmigaOS4 ecosystem, you can still have your way if you put in hard work and enthusiasm. From this viewpoint, it appears rather ironic that the international next-generation Amiga scene hasn’t even started contemplating a dedicated periodical to represent itself through – now that we know that users in Poland have had one for several years. Some food for thought perhaps. At any rate, the Polish lesson teaches us that things can be done if the rope is pulled in one direction. Thanks for the reminder, Amiga NG!

Outlining my programming activities in the previous blog post I also mentioned that I had been involved with the Amiga Developer project for quite some time. After the post went live a few people asked me whether it meant that I would work less on the project now that I develop my own software. The answer is no, not really. In fact, there is a good deal of synergy between Rear Window and the work I do for Amiga Developer, and the two efforts have benefited from each other.

I for sure am biased because of my personal stake, but I’ll say that one of the better things the Amiga Developer initiative has produced is the Enhancer Software Core classes: a free collection extending the standard GUI toolkit provided by the operating system. Indeed, the main reason why I like to promote the Core is because it brings new possibilities to Amiga GUI programming. So when I started working on my Rave audio editor, I knew I wanted to use the new classes on top of the traditional ones. What I didn’t know was that Rave would soon become an important test bed, a trial of fire in which the Core classes would have to prove themselves.

Regardless of how thoroughly you design it, a software component only reveals its true colours when used in real software. By which I mean not only that real-life use exposes bugs and drawbacks that went unnoticed at design stage or during beta testing. Actual use in software also tends to throw new light on how the component could work and what features might be missing. I’ll hazard a guess that a lot of the AmigaOS gadgetry has seen progress because a developer working on particular software was short of a particular feature. Or is it pure coincidence that the GUI toolkit received major updates while Simon Archer, one of the key OS developers, was working on his CodeBench IDE suite? I don’t think so. And that’s just one case in point.

Having access to the Amiga Developer source code repository I was, similarly to Simon, in the lucky position that I could shape the classes I’d decided to use in my software. As a matter of fact, all of the recent updates I have made to the Select Gadget (originally written by Massimo Tantignone) and the InfoData Gadget (Mark Ritter) were motivated by something that cropped up while I was working on Rave. And it won’t come as a surprise that my audio editor is also directly responsible for the very fresh addition to the Enhancer Software Core: the ToolBar Gadget class, which I have recently covered for the Amiga Developer Blog. Here’s how it all came about.

I have a habit of starting my projects by designing the GUI. Although in the end it usually bears little resemblance to the original version, I prefer to do it this way because seeing something tangible on the screen jogs my creativity. (It also tricks me into feeling a sense of accomplishment, despite the fact that the program doesn’t do a thing yet.) So I was sitting there designing an early toolbar for Rave when I once again realized how much I hate the standard SpeedBar Gadget, because it takes ages to set up. In an ensuing act of bravado I decided to put the work aside and write a custom toolbar gadget class: one that would be basic in features but extremely easy to get going. I thought, few programs use their toolbar for more than triggering action, so why not focus on the primary function? It turned out to be a relatively quick job, and it would have remained a one-off affair (and I would have no article to write now) if I hadn’t made a classic mistake: I shared my work with others.

In a way, I shot myself in the foot by offering the ToolBar Gadget as a contribution to the Enhancer Software pack. I fell prey to semantics, not realizing that if something is called “Enhancer”, people will invariably expect more features from it. Well, my gadget class didn’t have more features than the SpeedBar, it just represented a simpler alternative – which apparently didn’t come across as added value. The subsequent reactions ranged from indifference to downright scorn, and they were a painful lesson to learn. One fellow developer kindly sent a list of features my class absolutely needed to have before he even bothered to use it; isn’t team spirit great? But we Amiga programmers are renowned for our resilience (on top of the fact that we can cook a decent curry, which puts us in constant demand at registry offices), so I didn’t give up that easily and continued working on the class alongside the Rave project. This turned out to be a very sensible decision because as the program evolved, so did the ToolBar Gadget in response to my growing needs. Thus one feature led to another until one fine day (whew!) I finally felt that my dear little creation could no longer be blamed for not enhancing the Enhancer enough.

A brief look at the screenshot above may suggest that there is little visual difference between the ToolBar and the old SpeedBar. And yes, when the ToolBar Gadget saw its first public release, a few users seemed disappointed that the two classes didn’t look any different. On closer inspection, however, you’ll notice certain details that go beyond the default look and hint at the advanced configurability of the ToolBar. Most prominently, the new class features a borderless mode, which arguably looks more modern and helps reduce clutter in crowded GUIs. There are also smaller and less conspicuous improvements such as support for multiple image sets (and easy switching between them), adjustable inner padding of the toolbar buttons, or configurable style of the separator bars.

One feature I’m really proud to have implemented is overflow handling. What is that? Well, some toolbars can be quite long and take up a lot of space in the program window, which may complicate use (especially where screen estate is limited). Therefore, toolbar classes are typically designed as “collapsible” GUI elements, to allow shrinking the window to a smaller size. When the window becomes too small to fit all of the toolbar members, we get a situation called overflow. How this situation is handled depends on the particular class. For example, the SpeedBar Gadget employs a scrolling mechanism that is triggered by holding the SHIFT key and then dragging the mouse left/right (or up/down if the gadget is vertically oriented). I’ve always found this behaviour rather quirky and unintuitive, so I preferred a smarter solution. As the image below shows, the ToolBar Gadget reacts to overflow by displaying a selector button on the right. Clicking on the selector invokes a pop-up menu the individual items of which correspond to the toolbar members that are currently out of view. So even in a minimum-sized window it’s really quick and easy to access the program functions. (Potential naysayers will be happy to know that overflow handling is optional, so if you prefer to have a “static” toolbar that is always displayed in full, you simply don’t turn the feature on.)

Having finally released the updated ToolBar in October 2020 I though I’d give the Enhancer classes a rest for a while and fully concentrate on my audio editor, but as every seasoned programmer knows – man proposes, software disposes. Soon after I got down to business, working on Rave provoked another idea. Now, unlike in other spheres of human activity, ideas in programming can be really dangerous because they often lead to feature creep and, ultimately, projects that never get finished. Large software companies even hire professional hunters to locate staff programmers with ideas and shoot them on the spot. But as a humble freelancer I didn’t need to worry, and because the Christmas period promised some extra free time, I decided to have one more go at the ToolBar Gadget. So, what was this idea about?

Well, the main program toolbar in Rave contains a section with buttons that control the zoom of the waveform display. Originally I had the current zoom level indicated in the status bar at the bottom of the GUI, which was OK but somehow didn’t feel right. From the viewpoint of user interface design, I believe that if a GUI element controls a particular value, the value should preferably be displayed in the proximity of the controlling element, to have clear visual correspondence between them. So I started thinking: what if the zoom level value were displayed in the same toolbar section, i.e. next to the zoom buttons, rather than somewhere far below in the status bar? Of course, the ToolBar Gadget wasn’t exactly up to this: you could create a text-only button, you could even change the text on the fly, but it would still look and act as a button. What I needed was a new type of toolbar member, a read-only display area streamlined for dynamic text content. Luckily, the internal design of the gadget allows me to add pretty much anything (as long as it’s a BOOPSI object), so before the New Year chimed in I had the textbox member type ready and on the job. This is what it looks like in the current development version of Rave:

For good measure I also threw in support for colours and text styles, because it was clear to me that someone would ask for these features sooner or later. Now that I’m thinking about it, in the end I must have made the ToolBar one of the most versatile and configurable classes of the entire AmigaOS4 BOOPSI set. Why do I suddenly feel so tired?

All right, it’s getting long (and late), so time for some closing words. An old Slavic proverb says that you can’t sit on two chairs at the same time. And there’s a good deal of truth in it: working on two simultaneous projects often means that one will rob the other of your time and focus. On the other hand, projects can also inspire each other, grow together and produce a synergistic effect between them. This has worked very well for me: both the Enhancer classes and the Rave audio editor have greatly benefited from the synergy. I’m quite sure there will be more in the future. And I’ll be here to tell you, so keep an eye on the Rear Window!

I realize it’s high time I shed some light on my Amiga programming activities and on the software I’m developing at the moment. Pressed for time before Christmas I originally planned to write just a short heads-up note but because there’s a bit of a story behind it, I’ve decided to turn it into a regular blog post in the end.

The story begins in late 1980s. I took my first steps in programming on the infamous IQ 151, a bulky personal computer that was produced in the Eastern Bloc back then. The manufacturer of the machine must have had a weird sense of humour to name it this way because there was nothing intelligent about the computer in terms of technology, features, or the user experience it provided. But it was there at the right time, and the excitement and sense of adventure programming brought to my life stuck with me. To cultivate my newly-found passion my parents bought me a second-hand Commodore 64, where the marvellous Simons’ BASIC provided everything a budding programmer could possibly hope for on an 8-bit computer. It was great fun while it lasted.

Fast forward to the 90s. Unheard-of at the time, the multimedia capabilities of the Commodore Amiga blew my generation away. It was such an eye-opener that for a few years I kept my programming pretty much on the back burner; instead I got involved with music making for the demoscene, as I already explained in a previous post. But for various reasons my demo-making flame dwindled down towards the end of the decade, and I found myself more and more interested in producing something that others could use as a productivity tool rather than just watch for pleasure. This is when I finally learned the C language and delved into documentation on Amiga system programming. Yet with hindsight I can see I was still merely fooling around, and it wasn’t before I acquired my first AmigaOS4 system that I started producing real software for real users.

Encouraged by positive feedback on my first OS4 release, an English dictionary built upon Princeton University’s WordNet database, I went on to write the preferences editor for Thomas Wenzel’s AmigaAMP audio player. I also developed several plugins for the popular CD ripping software ADRipper, and when its author Adrien decided to quit the Amiga hobby, I took over the entire development and produced two major updates to the program. (Some achievement, considering that the original code documentation amounted to a dozen comments written in French!) Not long after that I was contacted by A-EON Technology, who invited me to join their new Amiga Developer initiative, a project that brings you the Enhancer Software and that I have been part of for more than five years now. My main responsibility on the team is the development and maintenance of new GUI classes – building blocks that extend the functionality of the AmigaOS Intuition system.

There’s no doubt that working alongside some of the most talented Amiga developers of today is a great learning experience, and I find my involvement rewarding in many ways. But while I have definitely enjoyed contributing to a team effort, I gradually realized that given the time constraints of family life, working on the project keeps me away from the productivity tools I wanted to make in the first place. At this point I started contemplating the idea of my very own, independent project that ultimately became the Rear Window.

As you would expect, the first question I asked myself was: “What kind of software do I actually want to develop?” Well, my academic and professional background is in languages and translation, so I initially thought I’d write something in the vein of WordNet – that is, a new dictionary, a lexical analyzer, or perhaps a translation tool. But then I remembered it was the multimedia aspect that drew me to the Amiga, and as a musician I could see logic in developing something related to audio. Incidentally, my old music-making passion was warming up again at the time and I was looking for an audio editor to use with my sample library. It didn’t take a lot of research to see that the current offering is not great: the existing editors either showed incompatibilities with OS4, choked on modern audio file types, or were otherwise too limited in features. But frustration often brings about good ideas, and so I finally had a plan and a sense of direction.

I’m now happy to report that after some eighteen months of mostly late-night work the new AmigaOS4 audio editor has progressed to a stage where I can present it as a working piece of software. The program is called Rave, as I wanted a short name bearing strong associations with music and freedom. (It is also close enough to wave in both spelling and pronunciation, which I find playful.) It’s still rather basic in features but a lot of work has gone under the hood, allowing me to easily extend the program within the modular framework it is built upon. And although it’s a little early to promise a particular release date, I’m pretty confident to say that the program is currently in beta rather than alpha stage. I might also add that I expect to be able to publish a sneak-peek preview in the first quarter of 2021. And of course that I’ll cover some of the program features in more detail in the subsequent blog posts!

For now, they say a picture is worth a thousand words, so why not have a look at a few preliminary screenshots?

And of course: Merry Christmas, Amigans!

Much of my creative activity in the 1990s was related to the Amiga demoscene. I was lucky to live in a city which, albeit small, concentrated enough local talent to have formed a full-fledged demo group called Vectors, which I joined in early 1993. Unlike many other demo groups, the members of which were often scattered across different cities or even countries, we could easily meet up in person to discuss things, work on our projects, or just have some serious fun with our Amigas. This gave us a strong sense of belonging, and I dare say that our creative endeavours were driven by the fact that we were pals, above all.

Last year some good soul remembered that Vectors would soon turn thirty, and we organized a get-together to celebrate the anniversary. Most of us hadn’t met for good twenty years, so I expected a brief and rather subdued social occasion attended by life-worn, pot-bellied family guys. To everyone’s surprise the event extended into the small hours, well past the time our function room was hired for. Demos ran rampant, monitors flickered, beer flowed like a river, so it was inevitable that someone would eventually stand up and say, “Yes, we can! Let’s make a new Vectors demo!”

The drunken idea would have been all buried and forgotten were it not for our trusty coder Defor (the tallest guy in the photo above), who sent us an e-mail a few months later saying “All right boys, so I’m working on the demo, remember? How about you make some graphics and music for it?” I immediately knew I was in trouble because I hadn’t composed any demo tune since 2000. So I first thought I’d just fish out some unused music I made in the 90s and be done with it. But as others picked up speed and kept showing new stuff, my cowardly decision became more and more embarrassing. I also couldn’t help noticing that my old Protracker modules sounded really horrible, considering today’s standards. So it was clear that my AmigaOne X5000, which I had mainly used for system programming and occasional gaming, would soon get a new task to prove itself.

AmigaOS4 is not short of music trackers, although the choice is naturally not as wide as on classic Amigas. After some experimenting I finally opted for MilkyTracker, which is actually a FastTracker 2 clone but can export songs in the Protracker format. Good – I had the right tool and now it was time to bite the bullet and do my piece of work. It’s not that I hadn’t composed any music in the previous two decades; in fact I ran a small production studio for a few years, but it was all PC-based and very MIDI-oriented, with the Steinberg Cubase sequencer being my staple software. So it naturally took me some time to put all my trust in the Amiga again and get back into the tracking mood. “Will I still enjoy it?”, I asked myself. “Will the final result be worth the effort? And will my wife not kill me when she sees what I’m doing?”

As it turned out, neither the Amiga nor the tracker paradigm were the roadblocks. But I had completely forgotten how limited Protracker was with audio samples! Although MilkyTracker was more than happy to import material from my sample collection (most of which are 16-bit stereo .wav files sampled at 44100 Hz), when working on a tune to be eventually saved in the .mod format you want to keep an eye on the Protracker specification right from the start, to avoid unwanted surprises at a later time. I learned something of a bitter lesson there before I finally decided to play it safe and just converted everything to 8-bit mono at 22050 Hz (i.e. half the original sample rate), which seems to have worked well. Compared to the sounds I used in my old songs, none of which were sampled above 16 kHz, I can hear that this project has really benefited from the increased sample rate and got the extra spark in the higher frequency range, allowing the drum track to stand out and making synth sounds more vivid. The individual instrument parts are more defined and the overall sound is less muffled. Apparently, good old 8-bit sound can still cut the mustard.

Once I got the samples in it was time to brush up my tracking skills, knowledge and techniques. To my surprise, after a few late-night sessions using the tracker was like wearing old shoes. It was still there! I even remembered many of the Protracker effect and control commands, which only testifies to the fact that human memory has a tendency to keep the most useless things of all. Anyway, to cut a long story short: I had the tune pretty much complete in about two weeks of burning the midnight oil. I spent some more time optimizing the song in order to get under the size limit imposed on me, for we had agreed that the demo would be a true retro piece running on a lowly Amiga 500 (with a 512 KB Fast RAM expansion as an afterthought). During the entire process MilkyTracker was a pleasure to work with and never crashed or locked up, which suggests that the port is a job very well done. I can certainly recommend the program to any AmigaOS4 user interested in making music for demos or games.

With all the artwork and code in place we finally released the demo at a local Amiga party held in late September, a real close shave because the government’s Covid-19 restrictions hit back the following week. We decided to call the demo Mindsurfin’, which I find a particularly apt name not only because of the laid-back atmosphere but also for the reason that working on the demo was one big trip down the memory lane. And there was one more thing in it for me personally. I was excited to see our labour of love run on a classic Amiga, knowing that my next-generation Amiga was so instrumental in the project. It felt like two worlds shaking hands in a much-delayed reunion.

Enough said, enough done. You can download Mindsurfin’ as an .adf image from the demoscene portal Pouët.net (which also hosts old Vectors productions, in case you were interested in what we did in our years of youthful folly). The demo has been tested on a genuine Commodore Amiga 500, on a Vampire V4 Standalone, and in various emulation environments including Amiga Forever and E-UAE. You can also watch it on YouTube as an alternative. Last but not least, a few people have asked me if the music .mod can be downloaded from somewhere, so I’ve made it available here for anyone interested.

Enjoy and spread the word!

Browsing through old diskmags always makes me notice how much Amiga-related writing I did in the 1990s. But of course: the Amiga was my computer of choice back then, I used it throughout the decade as my main productivity tool. I used the Digita Wordworth for all my written coursework, including the master’s thesis; I composed several dozen tunes for demoscene productions in Protracker; I took my first programming steps in GFA Basic and, later, Storm C… So there was a lot to write about, and writing about it was great fun.

I haven’t written anything since I rekindled my interest in Amigas around the year 2009. The usual pressures of life are largely at fault of course, but now I realize I’ve been using “next-generation” Amigas for longer than I actually used the classic ones – so I find it quite absurd that I’ve never tried to share my experience. In a fit of self-honesty I also admit to myself that I’ve secretly missed my writing all the time, hence this little blog.

The name

There are three reasons why I decided to call my blog Rear Window. First of all, I’m a big fan of Alfred Hitchcock’s film of the same name – it’s just pure cinematic class! Second, my Amigas and I spent many years in small rented rooms with a single window looking out on the backyard. Over time, this had become such a predictable coincidence that, at some point, I started calling every man-cave I moved into after the rear window it had. And third: a backyard full of old junk and memories is an arcane place, neglected and out of sight but calling for adventure and inviting explorers; a perfect metaphor for the Amiga world today!

I am, therefore, opening my Rear Window on the backyard. Let’s see what we can see there.
