This is instructions on how to build a 6-button footswitch for use with ZOIA’s control port. Included in the .zip is a build guide, excel spreadsheet and ZOIA patch for implementing the footswitch.
*1.1 Update*
Corrected a resistor value in the circuit diagram.
Included a sample and hold module on page 0 of the patch that could be used for preset functionality.

thanks for the idea. But I think your schematic has a wrong value for R5. It shows 500 Ohm when it should be in the ballpark of 2000 Ohm
Thanks! I’ve updated the manual with the correct value.
Hi. I haven’t seen any info on aux switches for the control port
I have a three button aux switch with no LeDs, can this be used with the control port?
Could I use the aux switches as a multi effects unit ? (Turning on and off effects).
