Try [switch~] to turn off dsp in the subpatch(es) ala:

[ 0 ( | [switch~]

You might need to add a small delay and ramp to avoid clicking.

Hi,

I have a headless raspberry pi that boots into a PD patch I created. (I control it with a midi wind controller and an FCB 1010 midi foot controller.) I have observed that bypassing certain sections of the patch with MIDI signals generated by the foot pedal board does not actually stop those sections of the patch from processing, and using CPU bandwidth.

I was wondering if it was possible to cease processing sections of a patch somehow? Maybe by stopping a sub-process or something? Alternatively, I was wondering if it was possible to load a different patch upon input of a certain midi program change?

Thanks!
