I think you're right.
The first bank of four voices runs off of a master clock and the
second bank of four voices is detuned from the master.
So unison mono should be able to be either Single (a single voice) or
Double mode (two voices detuned from each other). Any more than that
is redundant (unless we add a second filter - OK now we're getting a
bit out of hand).
Portamento is either mono (one voice only) or double (two voices per
note) with up to four sliding notes. Or Poly (up to eight
simultaneously sliding notes).
And wouldn't it be nice to be able to slide notes from high side and
low side into one note - simultaneously. Or apply LFO to either, one
inverted to the other.
Wow! This could take a while.
Mike.
