Though, I'd really like to keep everything tiny and fast since I originally made the whole thing for being used as a sound effects/game music engine for this game I'm still trying to finish, so I would rather not make it too heavy.
Well, I have a couple of thoughts I think the Klystrack now can easily cover the music / SFX for your game engine. If you bribe n00bstar with bug fixes / feature requests he will probably do some tunes for you! You freeze klystrack in its current form except for bugfixes and as n00bstar mentioned call it klysklassik or something.
I also don't know what is the expected end result since there already are much more robust trackers with support for VST, makes little sense to me to do the exact same thing as everyone else.
To be honest I feel Klystrack is already a really unique and interesting project. It doesnt emulate a particular chip really, it is more (in my opinion) inspired by a particular palette of sounds which are kind of similar to AHX / SID / Atari which makes it very unique. I think the tracker is 95 percent of the way to being a really really awesome tracker which I just love playing with. The sound design is awesome, the only reason I dont release any of the things I have written is cause they are kinda, uh, crappy. If it can have just a few more tweaks it would easily become my primary composition tool.
I see it as a modern retro synthesis tracker with a gorgeous interface and a fucking BEAST of a synth engine. That is an awesome niche to occupy!
