KBD Rate Scaling / VEL Rate Scaling
The KBD Rate Scaling (Keyboard Rate Scaling) control scales the duration
of each portion of the envelope according to the MIDI note number of the
trigger. The control works as follows: Starting from Middle C (MIDI note
number 60) the duration of each portion of the envelope is scaled by the
control's setting for all notes above and below middle C. For example, if the
scaling value is set to 1.00, then the envelope duration is doubled for every
octave below Middle C. Conversely, the envelope duration is halved for
every octave above Middle C. In this case, if the trigger note is one octave
below middle C then the envelope duration will be twice that of when Middle
C is the trigger note. If the trigger note is one octave above Middle C then
the envelope duration will be half that of when middle C is the trigger note. If
the KBD Rate Scaling (Keyboard Rate Scaling) control is set to 0.5 then the
same effect will occur, although in this case the envelope duration will be
halved for a note 2 octaves above Middle C, and doubled for a note 2
octaves below Middle C.
The VEL Rate Scaling (Velocity Rate Scaling) control scales the duration of
each portion of the envelope according to the MIDI note-on velocity of the
trigger note. Starting from a note-on velocity of 64, the duration of each
portion of the envelope is scaled by the control's setting for all note
velocities above and below 64. For example, if the scaling value is set to
1.00, then the envelope duration is doubled for every velocity increase of
12. Conversely, the envelope duration is halved for every velocity decrease
of 12. In this case, if the trigger note has a velocity of 76 then the envelope
duration will be twice that of when the trigger note is played with a velocity
of 64. If the trigger note velocity is 12 less that 64 then the envelope
duration will be half that of when the velocity of the trigger note was 64. If
the VEL Rate Scaling (Velocity Rate Scaling) control is set to 0.5 then the
same effect will occur although in this case the envelope duration will be
doubled for every velocity increase of 24, and halved for velocity decrease
24.
