Octal mode and the Track Assign menu
As you know, the Destination ol a Track can be any DX
Voice or MIDI channel - if your ОХ is in the Octal mode,
the Destination will read "DX А? thru "DX H" instead of
just "DX". This means that any Track can be set to play
any DX Voice (A thru Н.) By using the Track Assign
menu, you can also set a separate Transpose and
Velocity Curve/Level for each Voice.
Please note that for any Octal mode DX Voice to be
audible, you must have at least 2 notes of polyphony per
Voice and ihe volumes of each Voice must be set (see
the DX Voice menus under ENGINE button 29.)

Poly-unison and Random pitch
42
The Poly-unison and Random pitch parameters of your.
DX are slightly different in the Octal mode lif you are
unfamiliar with these two parameters, please refer to your
DX7I/DX7s owner's manual
for an explanation.) If you
select Poly-unison, your total polyphony will be reduced
108 notes (not 4, as in any other DX Voice mode) Also,
if you use the Random pitch parameter you may notice
that is effect will seem riche and more natural sounding
than in the other DX Voice modes.
For those who are familiar with Grey Matter's E! for he.

Octal mode and MIDI input
Of course, you can drive the Octal mode's 8 DX Voices
wilh external keyboards and sequencers through the DX's
MIDI IN port. However, there are some special ENGINE
features for using MIDI input while the DX is in the Octal
mode. See the discussion of the Direct MIDI input mode
on page 36.
Panning Octal mode voices on the DX7II
The normal Pan feature is disabled when you are in the
Octal mode: however, there is а "pseudo-Pan" available,
allowing you to specify which audio channel а DX Voice
will be output o. This 'pseudo-Pan* is done by the
allocation of notes using the DX Polyphony menu.
To activate the *pseudo-Pant, press the PAN button while
you are in the Performance mode. Now, when you play,
the DX Voices that have been allocated the first 8 notes
of polyphony will be voiced by one audio channel, while
the Voices that have been allocated the second group of
8 notes will be voiced by the other audio channel. By
experimenting with and adjusting the DX Polyphony
settings, you can have single or group Voices in true
stereo. (For more precise panning, make sure that Dy.
namic Voice Allocation is OFF)
