MIDI and Mode Setup 

Under the Configuration menu, there are the MIDI setup and Play Mode setup functions. 
 
The MIDI Channel (or Omni mode)  is selected by the Y/Right knob and by pressing the Data 
Knob.  Omni mode will make Ottava respond to MIDI not and CC on any channel. 
 
The Play Mode is set by the X/Left knob and by pressing the Data Button.  The Play Mode can 
be Monophonic or Duophonic.  In Monophonic mode, the last note pressed has precedence 
(plays) .  In Duophonic mode, the if only one note is played, both oscillators  will sound on that 
one note, much like the Monophonic mode, but if a second not is pressed (the other note is 
held) the oscillator2  will play at the new not and  oscillator 1 will play the last held note.   If two 
keys are played simultaneously, Osc 1 will take the low note and Osc 2, the high.
