External pedal + auto bypass effects = things randomly do not turn on/off and get stuck

[theElevators]

hello.  I have a preset where I'm controlling a bunch of things with the expression pedal 2.  Specifically:

 

heel position:

delay is on, vibrato is off, reverb is off.

 

toe:

delay is off, vibrato is on, reverb is on.

 

This is pretty straight-forward.  When the pedal is engaged past 5%, things get turned on/turned off.  The problems start when I connected an external pedal.  I wound up having all effects on: delay, vibrato and reverb.  Re-entering the preset resolved the issue.  Also I have not had the same issue when using the onboard expression pedal.

 

So the bug is definitely with the external pedal.  Pod Go gets overwhelmed, and things start working backwards.  Any tips, besides not using the external pedal?  That onboard pedal is so tiny and flimsy... oh well

 

This sorta stuff works on the Helix, and I actively use this trick without any issues, btw.
