I have the distance and drive back to where I want but I can't get it to save. For the momentary bypass I have a Boss FS-5u. I have both TRS and TS cables. It looks like for programming Bruce says you need TS. But for usage I have a TRS. My changes won't save. Hopefully I'm just doing something wrong.
I asked Guido Kirsch this very question last month and here was his response:
no, the Ventilator does not accept TRS jacks.
