1 more key please, then making it 13 keys.
That would be the key of H, right?
My singing stinks (can't sing Happy Birthday on key)
Maybe H will make me sound 'H'eavenly.
Seriously, 76 WITH an additional split point so that I can play, in 'split' second timing using a different instrument/voice settin, answering parts to the main right hand.
In example, upper (EXTRA OCTAVE) split set to a choir/vocal voicing to do Doo-wops, shoo-be-doops, etc.
