Descriptions of Parameters
System Parameters
Envelope Menu: Percussion Pitch Parameters
Three parameters control the pitch of the percussion effect:
Low Harmonic (Low Harm)
Controls which drawbar is used as the basis for the low harmonic of the percussion effect. The
actual pitch obtained depends on which drawbar you use. On an actual tone wheel organ, this is
Drawbar 4. You can use any of the nine drawbars. Whichever drawbar you use, it will affect the
pitch of the low harmonic only when percussion is on (the Zone 1 button is lit), and the low
harmonic is active (the Zone 4 button is off).
High Harmonic (High Harm)
Controls which drawbar is used as the basis for the high harmonic of the percussion effect. The
actual pitch obtained depends on which drawbar you use. On an actual tone wheel organ, this is
Drawbar 5. You can use any of the nine drawbars. Whichever drawbar you use, it will affect the
pitch of the high harmonic only when percussion is on (the Zone 1 button is lit), and the high
harmonic is active (the Zone 4 button is lit).
Steal Bar
Controls which drawbar is disabled (if any) when the percussion effect is turned on (the Zone 1
button is lit). On an unmodiÞed tone wheel organ, the ninth drawbar is the one disabled.
Possible values are
Drawbar1
Ð
Drawbar9
, and
None
.
The LFO Menu
The LFO parameters for KB3 programs are the same as those for Internal-Voices programs. See
The LFO Menu
on page 5-3.
System Parameters
There are two menus in the system parameters region of the front panel: Global and MIDI Recv.
The Global menu controls several features that affect the entire PC2, while the MIDI Recv menu
enables you to conÞgure each MIDI channel for use when the PC2 is receiving MIDI information
from an external source (typically a sequencer).
The Global Menu
Local Control
Controls the connection between the PC2Õs sound engine and its MIDI-generating components
(keyboard and physical controllers). Set Local Control to
On
(the default) when you want to be
able to play the PC2 from its own keyboard (as well as to control MIDI slaves). Set Local Control
to
Off
when the PC2 is receiving MIDI from an external source. This is particularly important
when youÕre using a sequencer, since youÕll most likely have MIDI cables going into the
sequencer from the PC2, and into the PC2 from the sequencer. This can cause notes to get
doubled if the Soft Thru or Play Thru feature of the sequencer is active.
