I've been playing around with VGM MM, making a couple of songs with instruments ripped from other games. But if you want something done right you have to do it yourself...or in my case, if I want it to sound right. So I messed around with the instrument editor some more, changing single parameters at a time and noting what changes. But that isn't enough, I need to know why these changes are taking place to get a better understanding so as to make instruments sound exactly as I want them to. Especially since the last change I made created an odd new effect that I have NO explanation for. Anyone know where I can find out more about FM synthesis with the YM2612 in mind? Or even just FM synthesis with 4 or more operators?
