Color the keys in function of the velocity

Hi devs,

watching one of the latest Kenny Gioia's videos

I thought one nice little touch would be to color the keys pressed with their velocity. The color scheme could be the same used in the MIDI editor for more coherence.
What do you think ?

With on that, count me in!

Also I would like to see:
· uniform keyboard layout for the virtual piano kbd and piano-roll
· custom note names (MIDI note events, mapping)

For example instead of A, B, C, D to use other glyphs or letters.
