The tune seems to work well barebones, but I want to comment a bunch of things, especially about usability:
- You shouldn't have a lot of instruments playing in #6 and #7 when there are other vacant spots available, as #6 and #7 are used for sound effects as well and they will interrupt the drums.
- Bass drum (@21) and snare drum (@10) are playing in different channels. Since when one plays, the other is silent, they should be merged into one channel for more ease on vacant channels. Instruments can be changed in one channel, no channels are specifically meant to only have one instrument.
- To have a slightly powerful snare, I think @29 might be better to use.
