Level = -63,...,+63
This value sets the velocity sensitivity for the PEG levels: the amount by these levels
(initial, attack, sustain, and release rates) vary in response to the velocity of the played
note.
Set the value to 0 to keep the levels the same for all velocities. Positive settings cause the
levels to increase as velocity increases, while negative settings cause the levels to de-
crease as velocity increases.
Range = -63,...,+63
This value sets the range for PEG pitch variation, in semitones.
This setting works in conjunction with the level settings at the PEGLevel page ( 200)
to determine how far the PEG levels are from the sample's basic pitch ( 198). If you set
the PEGLevel settings to maximum (+127 or -127), then the distance between each level
and the basic pitch will be equal to the number of semitones that you set here.
