USING THE PDS-3500 WITH A CONTINUOUS CONTROLLER PEDAL
The PEDAL STATUS number is really only necessary when you intend to use the PDS-3500 with a 0
to +5 volt controller pedal like the DOD FX-17. If you do not wish to use a continuous controller pedal
with the PDS-3500, the unit is programmed to the default value of the PEDAL STATUS number, pedal
disabled, indicated by "Pd" on the LED display. You may simply store the PROGRAM CHANGE number
and the MIDI CHANNEL number values without selecting the PEDAL STATUS number and the PDS-
3500 will disable the pedal function and not transmit any information relating to a continuous control-
ler.
Should you program a continuous controller definition into the PDS-3500, but not have the FX-17
plugged in, zero values will be transmitted. This will result in the minimum value for that controller be-
ing sent. The volume will be at the minimum, or there will be no modulation, or any of the other contin-
uous controllers won't work. The use of the PDS-3500 with the controller pedal allows you access to all
of the MIDI defined continuous controllers.
The PDS-3500 uses 7 bit resolution for the continuous controller function, and 8 bit resolution for
the pitch bend. This, combined with the coarseness of the foot controller, may not be of a sufficient res-
olution to perform some of the continuous controller functions well. An example may be pitch bend,
where the unit will toggle between two values and yield an unsatisfactory performance.
The following table shows some of the more useful definitions available. For a more complete list of
the currently accepted defined numbers, refer to the listing of the continuous controllers in the back of
the manual.
