Ability to trigger patterns externally

[vincentsky]

what controller cannot to CC - lsb - msb? that is the foundation of program / bank change, correct? and with that number of permutations you can cover a rather large parametric space

haha, you're correct.  I was thinking more generic like "using a KeyStep on Channel 16 to play a note and start different patterns simultaneously"  type of scenario. 

Otherwise, you're right, traditional use cases would be Program Change/NRPN/CC - just need to sort through the possible 128 value/resolution challenge above. Personally, I'd be ok with that range (limit)...or just skip every other row.    But I understand Thomas may not want a half-baked solution either.
