Oberheim Matrix-12 User Manual

PEDALS Like LEVER 1 and LEVER 2, Pedal control in the MATRIX-12 is non-dedicated as
well. PEDAL 1 and PEDAL 2 inputs on the synthesizer's rear panel
corresponding to the PED1 and PED2 modulation control in the Patch can be
routed to a multitude of Destinations. Because Pedal-type modulations are a
popular and necessary form of control, PEDAL 1 is normally used to control
Volume in the Patch and PEDAL 2 is used for Sustain, although these settings
can be reversed.
Volume control by a pedal is achieved by the use of a "continuous" pedal - a
rocker-type pedal that provides a "more-or-less" function. Sustain control by a
pedal, on the other hand, is obtained from a "switch" pedal - a momentary spring-
loaded pedal that provides an Mon/off function.
The versatile design of the MATRIX-12 does not limit you to using only a
continuous pedal in PEDAL 1 and a switch pedal in PEDAL 2. They can be
reversed if you are more comfortable with that arrangement. In addition, both can
be continuous or both can be switches if you like. Just remember that whever you
use PEDAL 1 in the Patch for modulation, the MATRIX-12 will "look" to whatever
is plugged into the PEDAL 1 jack for the control. The same applies to PEDAL 2
modulation in a Patch. This design consideration allows the MATRIX-12 to
achieve enormous flexibility in footpedal control.
In most other synthesizers, the Pedals1 functions are "hardwired" - permanently
routed in the design. Although this is convenienient Gust plug in the Pedals and
go), it it very restricting as you cannot do anything else with them. The MATRIX-12
treats the Pedals like the Levers - they are non-dedicated - so that you may use
them whenever continuous control or on/off switching is needed in the Patch.
Volume Control
As mentioned above, for simplicity we will consider PEDAL 1 as the source to be
used for volume control. The input on the rear panel will accept a two conductor
potentiometer-type pedal such as the Oberheim POB-X. This input will be
summed together with MIDI VOLUME information received via MIDI IN from a
Master controller set to transmit on MIDI Controller 7.
PEDAL 1 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 Volume pedal control. Although somewhat tedious, this design
provides unprecendented flexibility in that you are able to program different
amounts of Volume - or none at all - in each Patch.
Option #1
Just like the volume dynamics programming associated with introducing Velocity
in a Patch, PEDAL 1 routing can be used to affect either of the VCAs. In the
MATRIX-12, VCA 2 is the last circuit in the Patch before the sound is fed to the
synthesizer's AUDIO OUTPUTS. Its normal setting is 0 because it is almost always
modulated by ENV 2 - a common Source for providing loudness articulation.
Volume control is most effective when PEDAL 1 is applied to the AMP of ENV 2.
1. Select ENV 2 and set its AMP amount to 0.
2. Press the switch beneath AMP in the Upper PAGE MODIFIER Display
and assign PED1 as the Source.
