DS development > [help wanted] MIDI synth using soundfont + hardware

#164642 - theli - Tue Nov 11, 2008 5:13 pm

split from http://forum.gbadev.org/viewtopic.php?t=14959 since these are not much of announcements

well.... that's what i have for now (sounds better):
http://theli.ho.ua/temp/playmidi_sf2_no$gba.rar - for testing in no$gba (fscr image appended)
http://theli.ho.ua/temp/playmidi_sf2_hw.rar ( nds + data files)
http://theli.ho.ua/temp/playmidi_sf2.rar - source + data

and it hurts (yeah, sounds i have to listen to too) my head already sooo much....
any help is desperately needed!
anyone wants to work on this?

i want this for such projects as openttd, wolf3d, scummvm, doom and others (ports of old games which utilized midi hardware for music)
source removed up until the new devkitARM+libnds released
soundfont specs: http://connect.creativelabs.com/developer/SoundFont/sfspec21.pdf

ps: midi/mus parsers are not perfect for now (most midis won't play correctly) as main idea was to write a synth

i've edited first post to point to sourcecode
code is not very good but this is what i worked out for two days

#164774 - Lazy1 - Wed Nov 19, 2008 9:42 pm

E2M1 Sounds pretty good so far!

I'm not much with audio but I'll take a look anyway :D

i've updated builds... i've added simple MUS parser just to hear how doom's mus files would sound .. though i haven't progressed on synth ( as i have a close to zero knowledge of sound/music/synth :) )
btw, in binary builds there is a possibility to return to tune select by pressing B

#164873 - theli - Fri Nov 28, 2008 11:35 am

i've updated binary preview builds .. i slightly reduced cpu and memory usage.. finally tested on hardware and fixed some bugs which prevented this to work on hw...
now it sounds better.. but still far from "good"
also i've tested this with some bigger (4M - 10M) soundfonts .. should work (unless you press "yes" when asked if you want to preload all samples :) )

also, i removed sourcecode up until the new devkitARM+libnds are released

also, take into account that without preloading samples you'll get missing notes when playing tune for first time

ok, so i've had some free time and finally upgraded to latest devkitARM :)
so i've updated a source to compile with it ... surprisingly, it required only a several changes
so i've uploaded source back and put a link in first post...

still noone interested? :(
