Oberheim Matrix-12 User Manual

The MATRIX-12, unlike many other instruments, gives
you the option of turning MIDI Controllers ON or OFF
because there may be times that you will not want them to
be transmitted to the Slaves in your system or affect the
MATRIX-12 via MIDI IN. Also, the ON or OFF status of this
parameter does not affect the MATRIX-12's Local Control.
They are enabled automatically when KEYBOARD is
selected from the ZONE.
ECHO When the MATRIX-12 is a MIDI Slave, this parameter
permits the MIDI commands received by the MATRIX-12
sent from the Master controller to be combined with MIDI
information generated by the MATRIX-12 itself and
re-transmitted via the MATRIX-12's MIDI OUT. This
parameter is used to turn the MATRIX-12's MIDI ECHO
feature ON or OFF.
MIDI commands received by the MATRIX-12 as a Slave
are never sent via MIDI OUT normally. Under normal
conditions, MIDI information is simply passed along to
other slave instruments in the system via the
MATRIX-12's MIDI THRU port only. ECHO permits this to '
be defeated, but if two devices set to Echo MIDI
information are cross-connected, "MIDI feedback" - MIDI
data being regenerated between two instruments -will
occur until one of the MIDI cables is disconnected, or
ECHO is turned off.
• WhenON, MIDI ECHOmakes it possible to enhance the
control over the other slave instruments in the system by
combining what would normally be passed only to MIDI
THRU with MATRIX-12 generated MIDI information and
sending all of these commands to its MIDI OUT. Thus,
MIDI ECHO allows for the other slave instruments in the
line to be controlled from two "Masters" in a sense,
because ECHO uses the MIDI commands from both the
MATRIX-12 and its Master controller together.
• When OFF, the MATRIX-12 returns to normal MIDI
operation. MIDI THRU simply passes MIDI commands from
the Master controller to the other slaves unaffected by
any additional MIDI information generated by the
MATRIX-12. MIDI OUT transmits only those commands
originating from the MATRIX-12 itself.
Using MIDI ECHO
Since the design of the majority of MIDI synthesizers provide for a
single MIDI IN port, there is no method other than switching MIDI
cables or purchasing a MIDI MERGE device to change from Master
control to MATRIX-12 control over the other slaves. MIDI ECHO
makes it possible for the MATRIX-12 and its Master controller to
have complete control over the other slave instruments using only
one MIDI cable from the MATRIX-12.
