M-Audio PROKEYS 88SX [12/20] Pitch bend range

2.11.8 Sustain Pedal

If you connect a foot-switch pedal to the Sustain Pedal input, the pedal will send controller 64 on/off messages to your sound module, synthesizer

or virtual instrument. The Sustain Pedal when held affects all notes being played until the pedal is released.

2.11.9 Sostenuto Pedal

If you connect a foot-switch pedal to the Sostenuto Pedal input, the pedal will send controller 66 on/off messages to your sound module, synthesizer

or virtual instrument. The Sostenuto Pedal affects all notes held down when the pedal is engaged until the pedal is released.

2.11.10 Pitch Bend Range

The range of frequencies that your pitch bend can control can be altered, so long as the Pitch Bend Range message is supported by your sound

module or virtual instrument.

To change the range of the pitch bend, you need to assign either the slider, expression pedal or modulation wheel to controller 128 (see appendix C).

Taking the Modulation wheel as an example, the process is as follows:

< Press the Advanced Functions button.

< Press the Wheel assign function key, key F#3 (see Appendix B).

< Press white data entry keys, A3, B3 then A4 to enter the number ‘128’.

< Press C5 to accept the value and return to Performance mode.

< The Modulation wheel will now vary the range of the pitch shift obtainable from the Pitch Bend wheel.

2.12 Panic

Sometimes you may ﬁnd that the sound on your sound module or virtual instrument does not seem correct. Or, you may ﬁnd that notes get “stuck”

while on and will sound continuously. This may be because your sound module or synth did not properly receive a NOTE OFF message for some

reason. There may also be some controller settings that are altering the sound in a way you do not like. You can reset all controllers, and turn off

all notes from the ProKeys 88sx, as follows:

< Press the Advanced Functions button.

< Press the Panic key, key F#2 (see Appendix B).

< Performance mode will resume, and the message will be sent on the currently assigned MIDI channel.

Pressing this function key will send the ‘reset all controllers’ and the ‘all notes off’ MIDI messages.
