Oberheim Matrix-12 - Patch - Patch Changes; Systemx and Patch; System Exclusive

SYSTEMX is MIDI data that is transmitted and received
between instruments regardless of the Basic Channel
setting. System Exclusive data, therefore, is not
"channelized" (not associated with a particular MIDI
Channel).
PATCH "Patch Changes" - This parameter is treated
separately from other Controllers because there may be
many times when you would not want MIDI Patch
Changes to be transmitted or received.
Patch Changes occur when a new Patch is selected from
the MATRIX-12fs Keypad on the front panel. The Patch
Change command must be performed by typing a 2-digit
number on the Keypad - using the V1 and"-" keys to
change Patch Numbers are not sent to MIDI OUT. Any
instrument slaved to the M ATRIX-12 in the system set to
receive MIDI Patch Changes will respond by going to the
new Patch Number when this command is sent. This is
only an index number for the Patch; it has nothing to
do with the actual sound of the Patch itself. Similarly, if the
MATRIX-12 is a MIDI Slave, it will respond to a Patch
Change command from the Master controller.
• When turned ON (underlined^, the MATRIX-12 will
transmit and receive MIDI information that will cause
instruments in the system to change to another Patch
Number.
When the MATRIX-12 is a slave, if your Master controller
has MULTI (or Split/Double) Patch capability and it is
designed to send MULTI (Split/Double) Patch Program
Changes via MIDI, the MATRIX-12 will also respond to
these commands when PATCH is enabled.
• When turned OFF (de-underlined), the MATRIX-12 will
not transmit a MIDI Patch Number when you change
Patches and it will ignore commands to change Patches
from other instruments in the system.
SYSTEMX and PATCH
Operation with Oberheim Instruments
When operating two or more MATRIX-12s together, a MATRIX-12 and an
XPANDER, or a MATRIX-12 and an Oberheim Xk Keyboard Controller, you are
able to take advantage of the SINGLE Patch/MULTI-Patch capabilities and the
Oberheim System Exclusive messages when making Patch Changes via MIDI.
System Exclusive
When SYSTEMXls enabled, two MATRIX-12s connected via MIDI are able
to communicate with each other in virtually every way with a few
exceptions. Just be sure to enable SYSTEMXon both instruments. Any
operation involving all Patch Edit parameters, MASTER PAGE parameters and
MULTI-Patch parameters made on the Master MATRIX-12 will be transmitted
