VCF / VCA
08 & 1 8 KEYBOARD / PORTAMENTO
Portamento routing to the DCOs is selected in these parameters.
Portamento is described as a "sliding" between notes played on
from the Master controller. The specific operating parameters of
Portamento - its RATE, MOD BY VELOCITY, MODE, and LEGATO
select - are programmed in the RAMP
I
PORTAMENTO Sub-Page
discussed later in this section.
PORTA -
When this is selected, PORTAMENTO is routed
to the DCO.
KEYBD -
When this is selected, PORTAMENTO is turned
off and the MATRIX-GR will be controlled from the Master's
keyboard normally.
OFF
-
(available for DC02 ONLY) - This option disables the
Master control to DC02. This means that DC02 will play
the same pitch no matter what keys are played. This is
definitely used for effects.
09 & 1 9 KEY CLICK
An effect that can be used to add an audible "punch" or "bite" to
the beginning of a sound, KEY CLICK can be turned ON or OFF in
this parameter. The amount is preset at the factory. You may want
to experiment by using KEY CLICK with piano, vibes and other
percussive instruments just to name a few.
The VCF
I
VCA section of the MATRIX-GR is where the sound generated by
the DCOs is "tailored" by you to determine what the patch will finally sound
like. This section performs important functions such as determining the
volume between the two DCOs, controlling the harmonics (the overall
brightness of the sound) and adding dynamics to the patch.
VCF
stands for "Voltage Controlled Filter'' and is the circuit that gives you
very precise control over the harmonic content of the patch. In adjusting the
harmonic content, the VCF acts somewhat like a tone control but with much
more flexibility. After you have selected the waveforms for DC Os 1
&
2, the
VCF allows you to determine the tonality of the sound and articulate this
tone setting with Envelope #1 (abbreviated ENV1 ) and PRESSURE. It is in
the way you use ENV1 and PRESSU RE that dynamics are added to the
harmonics of the patch.
VCA,
which stands for "Voltage Controlled Amplifier'', is the circuit that
controls the final volume output of the patch. Two VCAs are designed into
the MATRIX-GR to provide an increased ability to control patch volume. As
you can see, we've included modulation routings of ENV2 and VELOCITY
which you can use to apply volume or loudness dynamics to the patch.
