MIDI functionalities

[ralfpopescu]

Multiple key mappings where keys represent chords. Chord voicings could include Jazz, Classical, Pop, Future/Retro, Blues, Power Chords, Disco, and custom intervals.

Arpeggiation, multiple modes include thumb up/down, pinky up/down, random, converge/diverge, etc.

Global BPM, quantized loops you can record. Mess with your friends loops with effects and adding your own midi information

Keyboard effects, activated by holding down a key (x?) and using arrow keys to change parameters (for example, filter frequency controlled by up/down, resonance by left/right)

Template midi files that set up jams for you, for example a blues template which plays a 12 bar blues pattern which everyone can play along to
