Aux Bend Up / Dwn ST

Use the Aux Bend Up / Dwn ST parameters to set the Aux Pitch Bend Up and Down
ranges in semitones. Aux Pitch Bend is controlled by controller destination 21, the default
destination for the Ribbon Controller.

Velocity Mode

The Velocity Mode parameter determines the method that the PC4 maps the keyboard's
strike velocity to MIDI velocity. Set to "Traditional" the keyboards velocity will translate to a
MIDI velocity depending how hard you strike it. With a setting of "Fixed", the velocity is set
to a pre-determined value regardless of how hard or soft the keyboard is played.
A setting of "Fixed" will remove some of the other Velocity settings in the MAIN page and
replace it with a parameter called Velocity that has range of values from 0 to 127.

Velocity Scale

The Velocity Scale parameter lets you amplify or diminish velocity response from -300%
to 300%. Normal response is 100%. Higher values make the keyboard more sensitive (you
don't need to play as hard to get higher MIDI velocities) while lower values make it less
sensitive (playing harder doesn't change MIDI velocity as much). You can also set the scale to
a negative number, in which case the velocity response is turned upside-down: playing harder
produces a softer sound and vice versa. This is useful for creating velocity-based crossfades
between zones.

Velocity Offset

The Velocity Offset parameter also changes the velocity response, but in a more direct way, by
adding or subtracting a constant to the key velocity.
For example, if this is set to 25 (assuming a scale of 100%), then 25 is added to the velocity
of every keystroke, usually making the sound that much louder. The softest possible keystroke
will have a value of 25, while a keystroke with velocity of 102 will produce the same sound
as a note with velocity 127 (102+25=127). Negative values diminish the response: a setting
of -25 means the loudest velocity available will be 102, while any keystroke 25 or below will
produce a velocity of 1 (a velocity value of zero has a special meaning in MIDI and cannot be
used for Note Ons).
You can think of Scale as being a proportional change to the velocity, while Offset is a linear
change. The maximum values for Offset are ±127.
