To _fully_ complete the SCI game development system, it will need a sound editor. I did state that I was planning on making one, so, if no one else makes one, I suppose I will. However, I'm not a musician, nor do I have experience with programming audio. If you can create an editor, or even a midi converter that works on more midi types, I will add it to SCI Studio and give you full credit.
I don't know too much about low level sound stuff, but I thinking that if you do it in Windows, you could let windows load the midi, and then convert the loaded file in the windows format (presuming it will do this).
I'm working more on bug removal and such. I don't plan on working on a sound editor until the bugs are fixed.
Also, if you can do the sound tools, I can do SCI Studio VGA sooner.
