VELOCITY
To reset an amount setting, simply select the VALUE X number in the Lower
PAGE MODIFIER display and press CLEAR. The display will change to show its
default setting. In most cases the new number displayed will be 0, but you
can expect to see a wide variety of defaults depending on what parameter you
are clearing. For example, you can use CLEAR to reset the five POINTs of a
Tracking Generator: 0,15,31,47 and 63.
In the section covering the PROGRAMMER, we also mentioned that pressing
CLEAR while holding STORE recalls the M ATRIX-12's Basic Patch called
OBERHEIM. This action is actually "clearing11 the Patch and is called "Patch
Initialize" on many other synthesizers.
"Velocity11 (VEL) refers to making dynamic changes in the sound by striking the
keys on the MATRIX-12fs keyboard rapidly or slowly (playing the keys harder or
softer). "Release Velocity" (RVEL) is the complimentary opposite of Velocity:
modulation is achieved depending on the speed in which keys are let go after
being played.
Vebcity modulation is also available when controlling the synthesizer from MIDI IN.
This assumes that the Master controller that you are using is Velocity- responsive.
If it is not, MIDI VELOCITY will not work. You should also check the Owner's
Manual to find out if your MIDI Master provides Release Velocity as well.
Creating Volume Dynamics with VELOCITY
The most common application of Velocity is its use in creating loudness dynamics.
In the MATRIX-12, VCA 1 is the first of two circuits in the Patch that concern
volume before the sound is fed to the synthesizer's AUDIO OUTPUTS. Its normal
setting is 63 because it feeds VCA 2 (commonly controlled by an Envelope to
provide loudness articulation). Velocity is best used when applied to VCA 1. In
this particular application, Vebcity is used to play the patch louder or quieter:
Option #1
1. Select the VCF/VCA Sub-Page and set its VCA1 amount to about 25.
2. Press the switch beneath VCA1 in the Upper PAGE MODIFIER Display
and assign VEL as the Source.
VALUE X: A setting of 0 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 and the VCA 1 amount is at 63, the
opposite effect occurs: volume decreases the faster you play notes and slow
playing keeps the volume close to maximum.
