Poly6 MIDI Interface Info		4/12/2018

MIDI channel can be set by holding one key down while powering up the Poly6.   
Low C selects channel 1, C# channel 2, etc.   
The 17th key selects OMNI mode.   
Arpeggiator clocking can be set the same way, using keys starting at middle C.  
Middle C selects local arp clocking (not MIDI, also the default setting).  
C# selects quarter note clocking,  D selects eighth note, D# selects sixteenth note, 
and E selects thirty-second note arp clocking.   
The top six keys can be used to set the MIDI note number that maps to the bottom key.   
Holding the top key at power-up sets the note number to press the bottom key to 60.   
The next key down selects 48.   The next key selects 36, etc.   36 would probably be 
the "normal" setting.  The MIDI channel, MIDI note range, and arp clocking settings 
are retained until set to different values using the same method.
