Pitch EG Parameters
The Pitch EG parameters determine how the pitch of a Part's Voice
changes over time. This lets you produce subtle or pronounced pitch
changes as a note is played.
In the example Pitch EG settings below, a played note is gradu-
ally bent up to its normal pitch, and kept there as the note is held.
When the note is released, the pitch rapidly climbs up.

NOTE
The Pitch EG parameters may have little or no effect, depending on the particular Voice used
and the settings made to the main EG parameters.
Selected Part and MIDI channel
This determines the initial pitch of the Part's Voice, when the note is
first played. A setting of 00 corresponds to normal pitch.
