Oberheim Matrix-12 User Manual

MIDI The extensive MIDI assignments of the MATRIX-12 are selected in this Page.
"MIDI" is the acronym for Musical Instrument Digital Interface. MIDI is a universally
accepted system of digital communication that allows you to hook up your
MATRIX-12 to other devices - synthesizers, sequencers, drum machines,
computers, etc. - as long as they are also equipped with a MIDI interface. MIDI
makes it possible to connect instruments made by different manufacturers.
Because your MATRIX-12 uses an internal computer (called a "microprocessor").
it is able to communicate through MIDI to other microprocessor based devices that
have this interface. MIDI, then, is a digital language that enables two or more MIDI-
equipped instruments to "talk" to each other.
In the MIDI Sub-Pages, you are able to determine when and what kind of
communication takes place and how it will occur. MIDI communication is
transmitted and received, and this occurs through channels - much the same as
radio or television, but using cables instead of antennas. Connecting two or more
MIDI devices together constitutes a MIDI "system".
MIDI Communication
With the exception of just two MIDI functions - individual Voice control from MIDI
IN in VASSIGN and MIDI Input selection in ZONE - programming the MIDI
control in the MATRIX-12 is accomplished in the Sub-Pages of the MIDI Page.
The MIDI parameters selected and programmed in these Sub-Pages are Global.
This is true for both SINGLE and MULTI Patches.
MIDI communication is divided into several categories. For our purposes in this
section of the manual, we will be concerned with three of these sub-groups:
• NOTES
Notes played on one instrument are played on the other(s) as well as
VELOCITY and RELEASE VELOCITY.
• CONTROLLERS
LEVER1 (or a Pitch Wheel from a Master connected to the
MATRIX-12fs MIDI IN) and LEVER2 (or a Vibrato Wheel), PEDAL1
(normally Volume) PEDAL2 (normally Sustain) and PRESSURE
(After-Touch) used on one will modulate the others in the MIDI system.
• PATCH CHANGES
The remaining performance control commonly used in MIDI
communication, the PATCH CHANGE command, is treated separately
by the MATRIX-12. The ensuing discussion clarify this.
