Control Delay LPF via external midi

Hoping someone can answer this! Maybe @Ess ?
The digitone manual states the delay LPF is cc73, but that conflicts with parameters on the synth tracks. (Cc 73 is also the filter env release time for synth tracks)

So on which midi channel do I access the Digitone Delay LPF?
(Am wanting to modulate the digitone delay LPF from an octatrack midi LFO.
Thanks!

I think you can assign the fx to a different midi channel in the midi settings.

Thankyou! Yep that appears to be it!
