Since the MIDI specification calls for a Pitch Bend Wheel to bend the Pitch of a Sound
both up and down, this Parameter is an absolute value only – it is neither positive
nor negative, merely a range amount.
To set the range that a MIDI Pitch Bend Wheel can alter the Pitch of a Sound, move
the cursor beneath the Parameter Value and then turn the Value encoder to set the
semitone range:
SND1:PITCH
PWHL>PITCH: 0 2
P4 The PITCH ENVELOPE TO PITCH Parameter
This Parameter determines how much the Pitch Envelope Function will affect the
Pitch of the current Sound. The default value is 00, meaning that the Pitch Envelope
has no effect on the Sound's Pitch. However, certain hand drums and even toms can
benefit from some "automatic pitch bend" which can be programmed with the Pitch
Envelope.
To set the amount that you wish the Pitch Envelope to modify the current Sound's
Pitch, move the cursor beneath the Parameter Value and then turn the Value encoder:
SND1:PITCH
PENV>PITCH: 5 0
Note that negative Values will "invert" the Envelope, allowing you to create very
esoteric pitch effects with the Pitch Envelope. Remember that "inverting" is not the
same as "reversing" – the envelope will still play in a forward direction (attack is still
attack, release is still release, etc.) but the Pitch will be modulated in the opposite
direction from a non-inverted (normal) envelope.

This Parameter may seem silly on a drum module, but do not
overlook the usefulness of pitch bending hand drums, especially
ethnic drums that are designed to change pitch such as udus or
talking drums.
