Ah, I was going to make a proper release thread for this. Well, seems that has already been taken care of :D
Ok, some additional info, then. First of all my apologies again for not releasing this earlier, but I didn't have it ready before Winter Chip and I thought it wouldn't be fair to release it half-way through.
Anyway, so what's new in teh Trio, aside from different sound, third channel and noise mode? Well, first of all, XMs created in OpenMPT should work now. Also, the compile scripts default to using MAME now, since MESS no longer exists as a seperate project. It's still possible to use MESS though, just edit the compile scripts accordingly. Also, the XM converter is now a stand-alone executable rather than a Perl script, so Perl is no longer required (Mac users will need to find a way to compile the converter from source, sorry bout that. If anybody provides a binary I'll gladly include it in the package). Other than that, the procedure is pretty much unchanged - set up MAME/MESS (grab the ROMs from Sleizsa/Sleizsa Duo I guess), compose music using the XM template included in the package, run compile script, done.
If you're missing that 8Khz whine, no prob, just crank up the duty cycle settings in main.asm and you'll have it back in no time :D
garvalf, yes, 4 channels is very likely doable. Also other stuff, like duty cycle envelopes, phasers, etc. But there are two problems with that. 1, we don't have an editor available, yet simulating complex stuff like phasers in XM is pretty much impossible. 2) Afaik MAME still only supports cartridge sizes up to 8KB, so the data format needs to be as compact as possible. That's why I decided against using variable duty cycles in Trio, even though it would have been entirely possible otherwise. Well, I'm not ruling out making a Sleizsa Quattro at some point in the future, but for now I've got some other projects to finish up. Like finishing my new album and getting a new HoustonTracker release done, for instance ;)
The taxman brings a prediction!
