Yes, if you set the 650 to the 2/2 voice group mode, with one of the voice
groups set to either the Unison or Unison Steal allocation mode, the first
note will play on two oscillators (voices). If two notes are played at
the same time then they will play on one oscillator (voice) each. So yes,
in this particular case the 650 works much like the Odyssey.
The 650 has 3 different unison modes. Here's a description of each:
∗ Solo Unison - only one note will play at a time, but all available
voices will play the same note. Useful for fat leads.
∗ Unison - the first note will play on all voices, the second note will
use half of the voices to play the second note, the third note (if there
are 3 or more voices available) will use 1/3 of the voices to play the
third note, and so on until there's one note playing on each voice. At
that point, additional notes are ignored until earlier notes are released,
in which case the voices are reallocated to the newer notes (but with no
new trigger).
∗ Unison Steal - same as Unison, until you play one more note than you
have voices. At that point, it "steals" the voice allocated to the first
note to play the most recent note (with a new trigger). If you release
the newest note (while still holding the first note), then the voice goes
back to the first note (but with no new trigger).
If this sounds complicated, it's a lot easier to understand w/ your ears.
Spend a minute playing with each voice allocation mode while looking at
the voice LEDs and listening. You'll quickly figure out how each mode
works, and how each one is musically useful.
