ok, first of all, the music update is great.
couple things:
fiddle seems to have slightly too much latency on the attack, and not enough sustain/release, not sure what the deal is here.
would be nice to have at the very least full octave +1 (high c/low c), i understand keys are limited. maybe instead of having the full octave have the ability to select a key and only show the proper 8 notes from that key. then maybe you would be able to play 3 full octaves (on key) at once with q-i,a-k,z-,
support for other keyboard layouts would, i'm sure, be appreciated.
additional instruments that would be great
drum - dried hide stretched over a wooden frame. only two or three different sounds possible.
some kind of horn - you know, some of those long trumpet like things, bonus points for attached flags.
additional flute type - kind of a bagpipe style, craft it with some dried hides and some bone, maybe you can call it a skin flute.
