Perhaps the potential adding of our own instruments?

[catx1]

Like example, we were to upload an .mp3 file (prob 100 KB or less. That'd be ~6 seconds 64 kbps), or series of those, and have options like "hey this is what a clarinet sounds like. it's this note and we should allow up to 2 octaves detune", or "hey, this is an addon, called the 10-bit drum kit (like example: NDS's Pokemon Black 2 / White 2 drum effects), it should be on G5, G#5, A6, A#6 and B6, et cetera..."

Ik its a lot of work on your guys' end but it'd be awesome if we had that, that way we wouldn't have a few or so requests to add instruments :3

Just a thought,
