External Triggers
In the MATRIX-GR, External Triggering takes the place of the
Master Controller when driving the Envelopes. The trigger source
is plugged into the PEDAL 2 jack on the back panel using a
standard guitar cord: a 2-conductor, sheilded cable with a
1 /4"
plug on the end that goes into the MATRIX-GR.
Suitable trigger sources for this purpose can be a footswitch or
any trigger source that provides a DC pulse of at least 20 ms.
(milliseconds) in width and an amplitude of +
1
to + 1 0 volts in order
to operate.
The External Trigger modes operate the same as their Keyboard
Trigger counterparts. Refer to the previous descriptions to find
out the operations of each different mode. The following list
deciphers the display abbreviations:
XTRIG
XMTRIG
XRESET
XMRST
"External Single Trig ger"
"External Multiple Trigger"
"External Trigger Reset"
"External Multiple Trigger Reset"
58, 68 & 78 ENVELOPE MODE
We already know that an Envelope receives a trigger to start its cycle.
How the Envelope completes its cycle is selected in this parameter.
NORM
"Normal":
The normal operating mode of an Envelope is to
complete Its cycle while a key or keys are being held down during the
DELAY, A TT ACK, DECAY and S USTAIN stages of its cycle. After the
keys are let go, the RELEASE stage finishes the Envelope. Holding
a key or keys is called "Gating" - the Envelope in NORM mode needs
a Gate to complete its cycle.
If the keys are let go at any time before the S USTAIN level is reached
(even during DELAY or A TT ACK), the Envelope goes immediately to
its RELEASE stage.
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 DECAY stage finishes. DADR otherwise operates the
same as NORM. Releasing keys during the ATTACK stage, for
instance, causes the Envelope to go immediately to its RELEASE
stage.
FREE
"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 breifly to start
the Envelope (give it a trigger) is sufficent to complete the cycle.
FREE, therefore, provides the Envelope with a Gate even though
the keys are let go.
