keyboard will produce data. For example, if Zone 1Õs Key Range is C3-C5 and you play C2 and
push down on the note, pressure messages will be sent from Zone 1. As with any other physical
controller, however, you can disable pressure in any Zone, or scale it or offset it differently in
the various Zones. It might help to think of pressure as a Òthird wheelÓ Ñ wheels operate in a
Zone regardless of Key Range, and so does pressure.
MIDI Controllers and Other Parameters
After youÕve selected which Zone and which physical controller to work with (using the cursor
buttons or Intuitive Entry), use the Ctrl Num parameter to choose what this controller will do.
Some of the controllers have default settings that are pre-programmed in all of the factory
Setups (of course, you can change them). You can select from the entire list of numbered MIDI
controllers, as well as other MIDI commands and some Òspecial functionsÓ. To move through
the list, you can use the Alpha wheel, or Intuitive Entry with any continuous controller, or call
up the ControllerÕs number with the numeric keypad.
Here are some of the common ÒtargetsÓ for each controller, in scrolling order:
• None (the controller does nothing)
• MIDI Controller messages 0-127. The most commonly used Controllers are:
¥ 1 Modulation (the default assignment on factory Setups for Wheel 2)
¥ 2 Breath Controller
¥ 4 Foot Control (the default for Pedal 2 and Slider C)
¥ 6 Data Entry Slider
¥ 7 Volume
¥ 10 Pan (stereo position) Ñ Pan messages on the PC88Õs internal sounds only affect the
beginnings of notes, and do not change notes that are being sustained.
¥ 11 Expression Ñ an attenuator for fading in and out (the default for Pedal 1)
¥ 64 Sustain (the default for Switch Pedal 1)
¥ 65 Portamento
¥ 66 Sostenuto Ñ it holds notes that are currently down, but not notes played
subsequently (the default for Switch Pedal 2)
¥ 67 Soft Ñ lowers the volume by a pre-set amount and may softens the timbre as well
¥ 69 Hold 2 or Freeze Ñ it freezes a synth envelope at its current state
¥ 72 Envelope Control (also called Sound Controller 3) Ñ shortens or lengthens the
envelope of a sound
¥ 91 Reverb Depth Ñ (the default for Slider A)
¥ 93 Effects Depth Ñ (the default for Slider B)
• The PC88 uses some MIDI Controllers in unique ways to edit effects (83, 90, 92, and 94)
and operate the Arpeggiator (116-119): see Chapters 6 and 7 for more. A detailed list of the
entire set of MIDI Controller messages appears in Appendix F.
• A number of Controllers can cause trouble if not used carefully, such as 0 (Bank Select),
and all of the ones above 119, which include All Sound Off (120), Reset All Controllers
(121), etc. Be warned.
• Pitch Up (128 on the numeric keypad) Ñ pitchbend commands of 64 and above. This is
the default assignment for Wheel 1 Up.
• Pitch Down (129 on the numeric keypad) Ñ pitchbend commands below 64, going
negatively. The default for Wheel 1 Down. Since Wheel 1 Up and Wheel 1 Down are
conÞgured separately, you can have all sorts of wild pitchbend combinations going in
various directions over the four Zones.
• Pressure (the MIDI command) (130)
• Tempo (131). You can use the PC88 to clock an external sequencer, and this parameter sets
the tempo by determining the speed of outgoing MIDI Clock messages. It can also set the
tempo of the internal Arpeggiator. The range is 20-300 beats per minute.
