How do I use a footswitch to change individual RT Controls?

Here’s an example using Program A004: ![Tricky Kit]!
1) Make sure you have your damper pedal plugged in to the Damper
jack.
2) Check the top-level K.RTC Page (1.1-4). Here, we can experiment a bit
and find that turning KARMA SW1 on/off brings in an additional drum
pattern for more complexity. We can also find that knob 8 controls
adding repeats to the beat. We will substitute foot switch control for
these.
3) (6.4-3) [Menu]->[K RT]->[DynMIDI]. Set the first row to look like this:
A/Damper #64 000/127 M RTParm Control
This routes the selected controller (Damper Pedal) into an RTParm
Control “matrix”.
4) (6.3-1) [Menu]->[K GE]->[GE P..4]. Here, we need to locate the parms
that we want to control with the pedal. We find that Parm #2 is the one
that is currently assigned to SW1. So instead, we assign it to “Dyn1”
(row 1 of the Dynamic MIDI settings we just set up. If we had used row 2
to make the damper assignment, we would set this to Dyn2.) Test it out
– you can now turn the additional drum pattern on/off with the damper.
5) (6.3-3) [GE P..12] Here we can locate Parm #9, Repetitions, which is
set to Knob 8. So we change this also to “Dyn1”, and now the pedal is
bringing in the extra pattern AND adding repeats. Want the repeats when the pedal is Off, and then no repeats when the pedal is On?
Change the Polarity setting here (Pol) to “-” and it will work backwards.
Note that if this were a melodic sort of Program (strings, for example),
you might want to use the Foot Switch Jack instead, so you could still
have a damper, or you might need to filter out the damper pedal from
doing its usual activity at the same time on (6.1-3) [Menu]->[KARM]->
[RxFilt]->Damper unchecked.
