I've looked in the forums and generally discussions about instruments are about being able to add your own music or play the instrument manually.
They're a bit of an overshooting as of now but mine is a simple function that could be added to the current instruments system:
- Left Mouse Button - Play the current tune
- Right Mouse Button - Skip to next tune
This would avoid the roulette while trying to play a specific tune, which is not much of a problem but is, mechanically, bit of an awkward experience.
It should either show the title of the tune you skip to (many players don't know what they're called) or you could be able to find out by playing it.
Holding RMB should make you play the tune that you've skipped to as you normally would with LMB.
