Oberheim Matrix-12 User Manual

EXPO 3 This curve is also derived from EXP01, but its range is
compressed even more than EXPO 2. This produces the
most gradual response for MIDI Velocity and Release
Velocity and has the least dynamic range.
Using MIDI Velocity and Release Velocity
You will notice several important and obvious differences when using VEL
and RVEL via MIDI IN, as opposed to the way they respond internally. As
stated in the beginning of this section, the Velocity and Release Velocity
responses that apply to the internal Voices is also sent to other MIDI
instruments in the system via MIDI OUT. These settings are made in the MISC
Sub-Page.
However, the MIDI Velocity and Release Velocity received by the MATRIX-12
via MIDI IN is scaled much simpler from the internal VEL and RVEL responses.
This is because MIDI IN Velocity is usually scaled at the source (the Master
instrument). If Velocity Scaling is not a separate function in your Master
Instrument, you will find that some experimentation may be required to get the
Master and the MATRIX-12 to respond in the precise way that you want.
This particular situation is especially noticeable when using a MIDI sequencer
to record and playback on the MATRIX-12. You may discover that recording
a track on the sequencer with MIDI OUT Velocity won't sound the same when
in playback (which uses the MIDI IN Velocity). Again, some experimentation is
required here but as a rule-of-thumb, the MIDI IN Velocity Scale called
LINEAR most closely approimates that of the internal Velocity SCALE 2.
The flow chart below depicts a visual representation of how Velocity is
processed internally as opposed to Velocity control received via MIDI IN. Note
the that the KEYBD In function provides the MISC Page Velocity
SENSITIVITY control that is not present in the MIDI IN function. This is
because Velocity Sensitivity via MIDI IN can only be set on the Master unit.
