27 VCA 1 VOLUME
This first-stage VCA sets the initial output of the patch. VALUE
range is O to +63 where O indicates no output or silence and 63 is
maximum output.
28 VCA 1 MOD BY VELOCITY
One of the more common applications of VELOCITY is its use in
creating loudness dynamics. VELOCITY refers to making subtle or
dramatic changes by striking the keys on the Master's keyboard
rapidly or slowly (playing the keys harder or softer) . This assumes
that the Master controller that you are using is Veloctty
responsive. If it is not, this parameter will not work.
In this parameter, VELOCITY is used to play the patch
louder
or
quieter.
VALUE range is from -63 to +63. A O setting indicates no
effect by VELOCITY. When positive Values are used, notes
played quickly will increase volume and slower notes will not. When
negative Values are used, the opposite effect occurs: volume
decreases the faster you play notes and slow playing keeps the
volume close to normal.
How "Volume" and "Velocity" Work
Parameters "27 VCA 1 VOLUME" and "28 VCA 1 MOD BY VELOCITY" work
hand-in-hand. If the Value of VCA 1 VOLUME is set to 63, Velocity will seem
to have little or no effect if you give it a positive Value. This is because at a
Value of 63, VCA 1 is set as loud as it will go and Velocity cannot make tt any
louder. Also, if VCA 1 is given low Values, positive Velocity settings will
require very hard playing all the time or some notes will seem to "drop out"
and not be heard. You should plan to spend some time experimenting to
find the right combination of Values to suit your particular need.
As you experiment, you may experience some results that you didn't
expect. This may be due to the fact that many of the MATRIX-BR's
modulations are inter-related and editing one parameter could possibly
affect another indirectly. One example of this is using VELOCITY on the
output of Envelope #2 ("66 AMP MOD BY VELOCITY") . Since ENV 2 is
routed to VCA2, Velocity in this case may affect VCA2 unexpectedly.
Although we will cover this in more detail later, VELOCITY performance also
relies on the Values you give it for "Scale" and "Sensitivity" (see MASTER
EDIT
I
KEYBOARD "40 VELOCITY SCALE" and "41 VELOCITY SENS.").
Using extremes in the available Values may yield unusable results. For
example, setting "27 VCA 1 VOLUME" to 0 and a +63 on "28 VCA 1 MOD
BY VELOCITY" will be almost useless if the Sensitivity is set to maximum.
The resulting dynamic range will be too wide to be of any real use.
