Oberheim Matrix-12 - Sustain

VALUE X: A setting of 0 indicates no effect by PEDAL 1 and the Patch will not
make any sound. When positive amounts are used, the pedal has more control.
The recommended setting for PED1 is +63.
Option #2
Another alternative in programming volume pedal control in the Patch is routing
PEDAL 1 to VCA1. VCA 1 is the first of two circuits in the Patch that concern
volume before the sound is fed to the synthesizer's AUDIO OUTPUTS. Its normal
setting is 63 because it feeds VCA 2. PEDAL 1 control may be applied to VCA 1.
1. Select the VCF/VCA Sub-Page and set its VCA 1 amount to 0.
2. Press the switch beneath VCA 1 in the Upper PAGE MODIFIER Display
and assign PED1 as the Source.
VALUE X: A setting of 0 indicates no effect by PEDAL 1 and the Patch will not
make any sound. When positive amounts are used, the pedal has more control.

Sustain
As mentioned above, for simplicity we will consider PEDAL 2 as the source to be
used for Sustain. The input on the rear panel will accept a two conductor switch-
type pedal such as the Oberheim FS-7. This input will be summed together with
MIDI SUSTAIN information received via MIDI IN from a Master controller set to
transmit on MIDI Controller 64.
PEDAL 2 as a Modulation Source is programmed individually for each SINGLE
Patch. This means that each SINGLE Patch must be set up one at a time to
recognize the Sustain pedal. Although somewhat tedious, this design provides
unprecendented flexibility in that you are able to program different amounts of
Sustain pedal control - or none at all - in each Patch.
Sustain is achieved by routing PEDAL 2 to the RELEASE stage of the two
Envelopes that are controlling VCF FREQ and VCA 2 AMP. By so doing, you
are using the pedal to extend the Release time which makes the sound take
longer to die out after the keys are let go.
PEDAL 2 routing to the Envelope modulating VCF FREQ (usually ENV1)
controls the rate at which the Patch's harmonics sustain. PEDAL 2 routing to
the VCA 2 Envelope (usually ENV 2) controls the rate at which the Patch's overall
loudness sustains.
1. Select ENV 1. Press the button beneath RELEASEln the display to
select it as the Destination.
2. Assign PED 2 as the Modulation Source. Set its VALUE X amount to +63.
Use a lower amount if a shorter sustain time is desired. Or, assign PED 2
twice if a longer sustain time is desired.
3. Select ENV 2. Press the button beneath RELEASEln the display to
select it as the Destination.
