Option #2
1. Select ENV1 and set its AMP amount to about 25.
2. VEL may now be applied to the AMP of ENV 1. Start with a setting of
+63.
The amount of Velocity may be adjusted to achieve the proper effect. You
should also remember that the initial AMP setting of 25 can be adjusted to
obtain the precise tonal response that you want.
Portamento and LAG Modulation by VELOCITY
The LAG RATE can be modulated by Velocity. When this parameter is used,
the speed in which notes are played from the MATRIX-12's Keyboard will change
the Rate. VALUE X range is from -63 to +63 where a setting of 0 indicates no
effect by Velocity. Using positive amounts slows the LAG RATE as keys are
played fasterto a maximum set by +63. Using negative amounts speeds up the
Rate as keys are played faster. Remember that if you are playing the M ATRIX-12
from MIDI IN and your Master controller is not Velocity responsive, this parameter
will not operate.
Envelope Modulation by VELOCITY and RELEASE VELOCITY
EXAMPLE #1
As outlined in previous examples, the AMP of the Envelopes can be increased
or decreased by the speed (or how "hard") that you play notes on the MATRIX-
12fs Keyboard. It is important to understand, as in our example, that the parameter
being modulated by the Envelope will be the one that will be finally affected by
Velocity. This is one of the exciting, and often confusing, features of Matrix
Modulation: when a Source is modulating a Destination parameter which is in turn
modulating a second Destination.
VALUE X: 0 indicates no effect on the output level of the Envelope by VEL.
When positive Values are used, the Amplitude is increased as keys are played
faster above the Envelope's AMP initial level. Remember that the higheryou set
the AMP, the less effect VELOCITY will have. A Value of +63 sets the maximum
positive amount.
When negative Values are used, the Amplitude is decreased below the initial
output level of the ENV the faster keys are played. A Value of -63 sets the
maximum negative amount.
EXAMPLE #2
Velocity and Release Velocity can also be used to change the timing of the
Envelopes. This is a very useful performance feature in that the articulation of the
VCF and the VCA by the Envelopes can be changed depending on your
playing style as you are playing.
A common and useful application of this is to modulate the ATTACK stage of the
VCF Frequency Envelope and the VCA 2 Envelope at the same time by a
negative VEL amount. As you play harder, the negative modulation shortens
the ATTACK time, adding "punch" to the sound. Positive amounts will add to
the Attack time, making it longer the harder you play.
