Turn KB Hold off "remotely"

[Ilosariph]

Hey there, I just bought a second hand nord stage 3. I am trying to play a synth solo (Panel A is a pad for chords and B is the lead). Because I need the pitch bend I turned on KB Hold for synth A so the chords stay while I use that. However, at the end of the solo I can't manage to turn off KB Hold in time as my hand is on the pith bend.
Is there a way to turn the KB Hold off with a foot switch or something? A sustain pedal works decently but the tiny gaps between chords don't sound great. A second Programm also works but is that really the best solution? I have an fcb1010 so something with midi or a foot switch would be easier (at least from my limited knowledge).

Never used it, but MIDI Implementation chart in NS3 User Manual states:
"Synth Keyboard Hold": CC 78
So You would need a Midi Foot Switch where you can set the Midi Control Channel to 78. Values should be 0 for Off and 128 for on (just guessing).
