I'm having a very specific issue with the current set of SNES music I am converting to MIDI. SNES music is sample based. As such the programmers for this specific game did some funky things with some percussion sounds. One in particular is a crash cymbal (nope, should be electric snare). To make a reverb-ed extended crash (snare hit), they start playing the sound, but then backtrack slightly and play a little more in to the sound, and continue until it fades away.
For a visual representation, say the normal sound plays sequentially over the numbers 1 through 16. (Each number is actually a memory address in the game each slightly further in to the sound effect)
The game will play it like this for the extended effect as one continuous sound:
1 2 3 4
2 3 4 5
3 4 5 6
4 5 6 7
13 14 15 16
I assume the answer is no, but is there a way to have something like this in a MIDI file, aside from actually applying extra reverb and echo to the initial instrument sound?
Currently I have 2 through 16 muted so I just get a single cymbal snare hit, which loses the punch that it needs to sound proper. If I leave them on, I just get a machine-gun cymbal (snare) sound.
