Expression Pedal Connection
(An Expression Pedal is not included with the product).
The Expression Pedal plug allows connection of a continuous controller-
type pedal. Normally, these pedals are referred to as ‘Expression Pedals’
or ‘Volume Pedals.’ This pedal can be used to vary the overall volume of
Instruments that support this feature.
Note that all of the internal instrument sounds will respond to the
Expression Pedal.
If you are using the ProKeys 88 as a MIDI controller, the Expression Pedal
also causes MIDI Controller 11 Messages to be sent out. External MIDI devices
may not respond to controller 11 messages. Check the MIDI implementation
charts provided with your other MIDI equipment.
Pitch Bend Wheel
The Pitch Bend Wheel is used to bend the pitch of a note up or down. The range of the Pitch Bend is not assignable. It will always
increase or decrease the sound by two whole steps (2 semitones).
Note that all of the internal instruments will respond to the Pitch Bend Wheel, except for the Ride Cymbal, which is not
affected by the Pitch Bend Wheel.
If you are using the ProKeys 88 as a MIDI controller, the Pitch Bend Wheel transmits MIDI Pitch Bend Messages as it is moved.
External MIDI devices may not respond to pitch bend messages. Check the MIDI implementation charts provided with your other
MIDI equipment.
Modulation Wheel
The Modulation Wheel controls either a vibrato or tremolo effect assigned to the instrument you are currently playing.
Note that not all of the internal instruments will respond to the Modulation Wheel. Piano 1 & 2, Clav, Strings, Warm Pad,
Basses, and Ride Cymbal will not respond to the Modulation Wheel.
If you are using the ProKeys 88 as a MIDI controller, the Modulation Wheel transmits MIDI Controller Message 1 as it is moved.
External MIDI devices may not respond to Controller 1 Messages. Check the MIDI implementation charts provided with your other
MIDI equipment.
Volume Faders
There are three Volume Faders – Master, Split, and Layer. The Master volume fader controls the overall volume of the ProKeys 88.
The Split fader controls the volume of the split instrument and the Layer fader controls the volume of the layer instrument. Split and
layer faders transmit MIDI controller 7 messages and the Master volume fader transmits a master volume sysex message
Equalizer Rotary Knobs
The Equalizer Knobs allow EQ control of the treble and bass of the main audio output separately. The treble and bass can be
cut by -12dB or boosted by +6dB (a total range of 18dB is provided) by turning the pot to the left or right of its center detent point,
respectively. Note that EQ control changes are not sent via MIDI.
The Treble Knob will control the high frequencies of the overall sound from your ProKeys 88. Increasing or decreasing the high
frequencies will make the overall sound more ‘tinny’ or ‘dull.’
The Bass Knob will control the low frequencies of the overall sound from your ProKeys 88. Increasing or decreasing the low
frequencies will make the overall sound ‘boomier’ or ‘less full.’
Instrument Buttons
These are 14 buttons that give direct access to the 14 instruments. When pressed, the LED will light to indicate that instrument is
selected and the keyboard is playing that instrument.
It is possible to alter the instrument’s octave, transpose setting, and MIDI channel by holding down the instrument’s button and
pressing the relevant function buttons accordingly. Octave and Transpose Functions are described in more detail on page 11.
If you are using the ProKeys 88 as a MIDI controller, when an Instrument Button is pressed a MIDI Program Change with Bank LSB
and MSB Messages will be sent out.
This Program Change defaults to Bank MSB 0, LSB 0 and Program Change 0, 1, 2, 4, 5, 7, 8, 11, 16, 17, 32, 33, 48, 89, and 119,
respectively. However, you can alter the assignment of what Bank and Program Changes are transmitted out over MIDI by pressing
the two MIDI buttons (Bank LSB and Bank MSB) together (labeled “STORE”). Store is described on page 12.
The 14 instrument programs have been assigned to the appropriate GM program numbers to comply with GM level 1.
Performance Tip #4
New Age Setup 2
– Select E.Bass and transpose it up
two octaves. Layer it with the E. Piano 1. Split the
keyboard and also assign the E. Bass on the left side of
the keyboard as well. Add effects to suit your taste. The
bell-like tones in the right hand offer a very ethereal
and unique tone. Add effects to suit your taste here as
well. Try substituting the FM Piano 1, or the Wurly
program (E. Piano 2) for the E. Piano 1 program for
some interesting variations.
