Oberheim Matrix-12 - Keypad; MIDI Patch Changes

KEYPAD
The Keypad permits you to select any Patch in the M ATRIX-12's memory and
select a Patch Number when using STORE to write a Patch into memory.
When in SINGLE PATCH Mode, the Keypad's numeric buttons allow you select
any of the synthesizer's 100 SINGLE Patches numbered S00 through S99.
When in MULTI PATCH Mode, the Keypad's numeric buttons allow you select any
of the synthesizer's 100 MULTI Patches numbered MOO through M99.
The V and"-" buttons have two Modes of operation depending on the status
of the CHAIN function (refer to the operation of CHAIN on Page 52):
• When CHAIN is OFF, the V button advances through the Patches in
numerical order each time the button is pressed once. The"-" button is
used to reverse through the Patches each'time it is pressed once. If either
button is pressed and held down, the MATRIX-i 2 will advance or reverse
automatically through the Patches, one after another, until the button is let
go.
• If CHAIN is ON or in SLAVE, the 'V button advances and the"-"
button reverses through the Patches as they have been arranged in the
Chain program.
Thus, theff +" and" -" buttons can either advance or reverse through the
Patches in Numerical order or in the CHAIN order.
The action of the ADVANCE CHAIN footswitch and the V and"-" buttons are
not normally transmitted and received via MIDI by the MATRIX-12. See the
descriptions below for detailed information.
MIDI Patch Changes -
Operation with Oberheim Instruments
(Another MATRIX-12 or an XPANDER)
• When using the MIDI Patch Change function, both Oberheim instruments
must have SYSTEMX (System Exclusive) and PATCH\n the MIDI
ENABLES Sub-Page selected in order for the Slave Oberheim to
respond to the Master's switching between SINGLE Patch Mode and
MULTI Patch Mode.
• SYSTEMX must also be enabled on both the Master and Slave
Oberheim instruments for MIDI Patch Changes to occur when using the
ADVANCE CHAIN footswitch or theV and"-" buttons on the Master
Oberheim.
• If CHAIN is being used on the Master Oberheim, it will send MIDI Patch
Numbers to the Slave Oberheim on the Basic Channel when the
ADVANCE CHAIN footswitch or the"+" and"-" buttons are used. Just be
