Hey. Well I made this thread in a different forum a while ago and thought maybe The Pit would like it? Anyway you just have to make a song using GP4/5 etc thats ridiculously fast. Try to only use 16th, 32nd and 64th notes.
If it's been done before or you think it's a seriously bad idea just ignore the thread and dont murder me well have fun!
couldnt you just up the tempo instead of using all 16th/32nd/64th notes?
You could use 32nd notes at 40bpm, and it would be the same as 8ths at 160bpm.

Using 32nds and 64ths doesn't necessarily mean that it's going to be fast.

^^^Pretty much what he said.
