Oberheim Matrix-12 - Assign; Zone X

If OFFis selected, that Voice is removed from the stereo LEFT and RIGHT outputs
as well as the MONO. If your M ATRIX-12 has ben retro-fitted with the optional
Individual Voice Outputs kit, the OFF position routes the audio output of that
Voice to its individual output jack located on the M ATRIX-12's left walnut
endpiece.
V. ASSIGN
As with SINGLE PATCH Mode, it is in this Sub-Page where the Voices are given
("assigned") their source of control, either from the M ATRIX-12's own Keyboard
or from incoming MIDI notes. In order for the MATRIX-12 to play its
Voices, you must tell the Voices what control source (either the
Keyboard or MIDI IN) that you plan to use to play them. This is
accomplished with V. ASSIGN.
In the V. ASSIGN Sub-Page, you have six Voices displayed in the Upper window
with their corresponding control sources in the Lower one. Use the VOICES 1 -
6/VOICES 7-12 button in the PROGRAMMER section to switch Voice Banks as
you are assigning the Voices.
In this Sub-Page, you have no less than 22 sources of playing control for each
Voice: any one of six Zones or MIDI Channels 1 through 16. Turn any one of the
six knobs to view these available control options.
Selecting a MIDI Channel for a Voice removes it from Keyboard control. The Voice
can only be played monophonically from another instrument connected to the
MATRIX-12's MIDI IN jack if it is assigned to a MIDI Channel. This is referred to as
the MIDI MONO Mode -one Voice being played from one MIDI Channel.
Selecting a Zone for a Voice allows it to be played from the Keyboard or from MIDI
(Zones can also have MIDI IN control as we will cover in a moment). Thus, if a Voice
is assigned directly to a MIDI Channel in this Sub-Page, it by-passes the Zones
(and therefore the Keyboard) and gives up its ability to play polyphonically.
If two or more Voices are assigned to a Zone, they will play polyphonically within
that Zone. Thus, a Zone is the way to group Voices so that they will play
polyphonically-either from the Keyboard or from MIDI IN.
ZONEX
A Zone is the way to play two or more of the MATRIX-12's Voices
polyphonically. Conceptually, a Zone can be thought of as a "Voice Module"
where Voices are assigned to be grouped together in order to be played
polyphonically. But keep in mind that it is simple logic that if only one Voice is
assigned to a Zone, it will only play monophonically in that Zone. Another way that
Voices en be set to play monophonically is by setting the MODEoi the Zone to
any of three unison ("UNI -") modes.
Press ZONE X and the Upper PAGE MODIFIER display reads:
SELECT ZONE FROM 1 TO 6
Pressing an X SELECT button from 1 to 6 will select that Zone. You can switch
among the six Zones with the X SELECT buttons. Pressing the ZONE X button
twice recalls the last Zone that was selected.
