I would like to use a continuous control pedal to control some aspect of the sound. How do I set things up?
By default, the C Pedal acts as MIDI Expression (volume swell) for the MAIN zone, but it can be reprogrammed to do a variety of things, separately for each zone, including controlling the leslie effect on organ presets, tremolo depth, vibrato, etc.
The process for assigning the control pedal is the same as the knobs (detailed on pg. 4-12 of the manual).
With a compatible pedal connected, here are the basic steps:
How to read this screen? These settings indicate that currently in Zone 1 the CC Pedal is assigned to cc#11 Expression.
Zone:1 CC Pedal
Ctrl Num: 11 Express
Repeat the above as necessary for additional zones and/or Setups.
** Regarding what CC codes to use, check out Appendix B in the manual. There you will find custom controller tables, one per on-board program detailing what the various physical controllers do per program by default. By knowing the MIDI CC#'s for each, things can easily be reprogrammed to suit your application.
Here is the list of default physical controller CC assignments used by the SP3X:
Physical Controller MIDI CC# Knob A cc#6 Knob B cc#13 Knob C cc#22 Knob D cc#23 PitchWheel pitch up/dn ModWheel cc#1 FtSw1 cc#64 FtSw2 cc#66 CCPedal cc#11
For ex., let's say you wanted to control the tremolo depth on program 17 Serious Classic. In the manual, Appendix B, you will note Tremolo Depth is activated by ModWheel (MW). Cross referencing that with the defaults table above table, note ModWheel is cc#1.
So by assigning the CC Pedal to cc#1 in step 3 above, you are basically turning the CC Pedal into the ModWheel and thus able to control the same things with your foot that you can with your hand on the Mwheel.
