INSTRUMENT GLOBAL SECTION
Pitch Bend Range: Instrument Global settings apply to all regions
and dimensions of the instrument currently being edited. You can set
the Pitch Bend Range between 0 and 12 semitones (half-steps). The
Pitch Bend Range value represents both the upward and downward
transposition boundaries.

Piano Release Mode: This option is intended for Acoustic Piano
sample libraries. On an actual acoustic piano, you can step on the
sustain pedal very quickly after releasing a note and hear some string
resonance. Enabling this option emulates that phenomenon within
GVI using an instrument’s pedal down samples. This option is only needed for piano libraries
that use actual pedal down samples.
