Quick and dirty first pass at a class for the Akai MPD24

Jeff C. uses just one scene, so no switching

supports cc, notes, aftertouch, sysex. 

sysex is with MIDI.sysex - very dirty! 

test all kinds: 

(

m = MPD24Ktl.new;

// m.dump;

m.mapCC(\k1, { 'yo!'.postln });

m.mapCC(\sl6, { |val| val.postln });

// vel is scaled from 0 - 127

m.mapNoteOn(36, { |note, vel| [\noteOn, note, vel, "boom"].postln });

m.mapNoteOn(39, { |note, vel| [\noteOn, note, vel, "tchak"].postln });

m.mapNoteOff(36, { |note, vel| [\noteOff, note, vel, "moob"].postln });

// sends mono touch only. 

m.mapTouch({ |val| [\press, val].postln });

m.mapTrans(\fwd, { \fwd.postln });

m.mapTrans(\rew, { \rew.postln });

m.mapTrans(\rec, { \rec.postln });

m.mapTrans(\play, { \play.postln });

m.mapTrans(\stop, { \stop.postln });
