I believe the following is the option I used (no longer have that pedal to verify:)
"PASS-THRU CONNECTION (TOP SETTING) SWAPPED PASS-THRU CONNECTION (BOTTOM SETTING) The top switch position provides foot switches that function exactly like the ones on a stock mini-VENT – except that they can be placed in another location. A 3-switch pedal can be used to provide dedicated switches for each function (Speed, Stop, Bypass). Tip: Toggles the Speed between Chorale (slow) and Tremolo (fast) Ring: Toggles between Bypass and Effect settings Tip+Ring: Selects Stop speed The bottom switch position works the same, except that the Ring and Tip+Ring functions are swapped. This makes it easier to select Stop speed with a 2-position pedal, moving Bypass to the more complicated two-switch press. Tip: Toggles the Speed between Chorale and Tremolo Ring: Selects Stop speed Tip+Ring: Toggles between Bypass and Effect settings A 3-wire cable with a TRS plug on the mini-VENT side is required to connect to the control pedal, wired as in Figure 2. The Mini-Remote senses the polarity of the switches (normally-open or normally-closed); however, the polarity types cannot be mixed. If no switch is plugged in at startup, the Mini-Remote will assume that the switches are normally-open polarity."
I had a dual momentary footswitch plugged into the MiniVent that worked like the following after programming:
Right switch toggles Fast. Left switch short press chooses Stop or Chorale. Long left switch press was Bypass.
