The crest of a Rave

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!

Back on track(ing)

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 Pouë (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!

Opening the Rear Window…

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.
