Oberheim Matrix-12 User Manual

The MATRIX-12 enables you to set 14 MIDI assignments grouped into 6 MIDI
headings described in the following pages. These six headings are:
CHANNEL CTRLS ENABLES SEND RESET MUTE
CHANNEL Otherwize referred to as the "Basic Channel", this parameter
selects the transmitting and receiving MIDI Channel for the
MATRIX-12. VALUE X selects any one of the available MIDI
Channels numbered 1 through 16.
The main thing to keep in mind is that if the Master instrument in
a MIDI system is transmitting on a certain channel, the receiving
instruments must also be set to that channel, or be in OMNI
Mode, for MIDI communication to take place. In the MATRIX-12,
these "receiving instruments" are the 12 Voices. Since they
can be controlled independently, each of the MATRIX-12's
Voices can be regarded as an "instrument". If the Voices are
assigned to one or more ZONEs to be played polyphonically,
each ZONE is a "receiving instrument".
The Basic Channels are concerned primarily with transmitting
and receiving Notes and Controllers. There are, however, a few
details you must observe:
RECEIVE MIDI IN
When MIDI IN is used, the MATRIX-12 is considered a SLAVE
and will receive Notes and Controllers on the MIDI Channel
that you specify in VASSIGNor ZONE. Thus, the MIDI
Channel(s) selected for the Voices in VASSIGN or
ZONE will be used by the MATRIX-12 as the "Basic
Chanriel(s)" for those Voices assigned to them.
PATCH CHANGES, on the other hand (because they are
treated separately), are received on the Basic Channel that has
been set in this parameter and not on the ZONEs channel.
As an example, assume that the Basic Channel of the
MATRIX-12 is set in this parameter to 2. If all 12 Voices are
assigned to ZONE 3 and ZONE 3*s CHANNEL setting is
Channel 6, Channel 6 is the one that will be used for Notes and
Controllers but PATCH CHANGES will still be received on
Channel 2. Thus, Patch Changes are global commands and
Notes and Controllers are tied in to the ZONES or individual
channel settings in VASSIGN.
Summary
If the CHANNEL of the ZONE that is being used to receive is
set to OMNI, it will receive Notes and Controllers on all channels.
If the ZONE is set to a single MIDI Channel, that channel is the
- one used for receiving Notes and Controllers and Patch Change
commands will still only take place on the Basic Channel.
