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.
