Oberheim Matrix-12 - Trigger Modes; Keyboard Triggers; External Triggers

FREERUN This mode causes the Envelope to complete its entire cycle
even if the key or keys are released before the SUSTAIN
level is reached. Simply tapping a key very briefly to start the
Envelope (give it a trigger) is sufficent to complete the cycle.
FREERUN'therefore, provides the Envelope with a Gate
even though the keys are let go.
DADR "Delay-Attack-Decay-Release" This mode causes the
Envelope to skip its SUSTAIN portion while Gated (keys are
being held down). This has the same effect as if you release
the keys as soon as the DEC A /stage finishes. DADR
otherwise operates the same as in the normal operating
mode: Releasing the keys during the ATTACK stage, for
instance, causes the Envelope to go immediately to its
RELEASEstage.
You can select any one or any combination of two or three Modes for a variety of
Envelope operations. As an example, if all three are selected, this combines the
action of DADR and FREERUNwhlch will flESETwhenever the Voice gets a
new trigger. The DADR mode will complete its cycle (DADR Is Gated by the
action of FREERUN} even if the keys are released before the DECA /stage is
finished - and will RESETUom 0 if the Voice is played again in mid-cycle.
Trigger MODES
As stated in the introduction to this Sub-Page, an Envelope starts its cycle when it
receives a trigger pulse. In this parameter, we select between using the MATRIX-
12's Keyboard (or MIDI IN from a Master controller) as the source to start the
Envelopes1 cycles or External triggers to accomplish this. There are several types
of Triggers forthis purpose:
Keyboard Triggers
The following two Modes pertain to playing the MATRIX-12 from its own Keyboard
or from MIDI IN from a Master controller:
SINGLE "Single Trigger" - The Envelope will be activated for a
Voice only if that Voice is not already playing. This means
that if you are holding a key down, the Envelope for that
Voice will not start again (won't get a new trigger) until you let
go of the key and play the same Voice again. This means
that, when the ZONE for the Voices in Unison or controlled
by a single MIDI Channel, playing Staccato generates new
triggers and playing Legato does not.
MULTI "Multiple Trigger" - The Envelope will be activated any
time a new key is played. Playing Staccato or Legato will
always generate a new trigger. Keep in mind that this is per
Voice -the Multi Trigger will be generated on a Voice that is
already playing when this same Voice is played again.
External Triggers
In the MATRIX-12, External Triggering can take the place of the Keyboard when
driving the Envelopes. The trigger source is plugged into the TRIGGER IN jack on
the back panel using a standard guitar cord: a 2-conductor, shieded cable with a
1/4M plug on the end that goes into the MATRIX-12.
