Music has long been a problem in homemade SCI games, at least for me.
I have settled with using VDMsound and changing my sound driver to mpumidi.drv because the gm.drv jumbles up certain instruments.
I use Anvil to make a midi file and SoundBox to convert the midi to a SCI sound file, but I haven't yet found a way to make the sound faithful to the midi.
VDMsound keeps the instruments in tact, but the tempo is shaky, sometimes slow and sometimes fast...which can be irritating!
Does anyone have any info on getting music to work correctly and easily?
