Oberheim Matrix-12 User Manual

VELOCITY There are two Sub-Pages in the MATRIX-12 devoted to
the setting of the synthesizer's response to Velocity. In
the MISC Page, the controls are used to set the
MATRIX-12's Velocity reponse to its own Voices
internally and as Velocity is transmitted via MIDI OUT.
In this Sub-Page, you are able to determine the
MATRIX-12's response to Velocity when used via
MIDI IN.
This Sub-Page constitutes a separate set of Velocity
scales for MIDI IN because Velocity information received
from MIDI is usually scaled at the source. Therefore a
simpler MIDI IN response system is utilized. This
Sub-Page permits the scaling of MIDI IN Velocity in four
different ways.
When selecting the desired MIDI Velocity Scale, just
remember that you are selecting the scaling for both
Attack Velocity (titled simply VELOCITY) and RELEASE
VELOCITY. If you refer to the discussion of Notes and
Controllers on Page 54 of this manual, you will
remember that VELOCITY and RELEASE VELOCITY are
transmitted and received with MIDI Notes on the Basic
Channel. This Sub-Page, therefore, concerns the
receiving of VELOCITY and RELEASE VELOCITY via
MIDI. Refer to the section on Page 69 for information on
scaling Velocity for the MATRIX-12 internally and
transmitting it from MIDI OUT.
VELOCITY is a measure of speed. It is the term used to
describe the speed in which keys are played - or how
hard they are played - on the Keyboard, transmitted by
the MATRIX-12 to MIDI OUT or received by the
MATRIX-12 from MIDI IN. RELEASE VELOCITY is how
fast the keys are let go once they have been played. This
Sub-Page lets you tailorthe MIDI IN reponse of your
playing style to achieve a wide variety of results.
LINEAR This response curve causes received VEL and RVEL to
act in a linear fashion - striking the keys twice as hard on
the Master controller produces twice the output on the
MATRIX-12.
EXPO 1 This response curve is exponential, and responds much
like the human ear percieves sound - striking the keys
twice as hard produces 10 times the output. This scale
produces the most dynamic range for VEL and RVEL in
the MATRIX-12.
EXPO 2 This response is also exponential, like EXP01, but its
range is compressed to achieve a less dramatic effect.
There is more resolution in the middle of its range which
makes it very similar to the Scales used for the internal
VEL and RVEL scaling.
