This happened to me also. I have a 3x momentary switch pedal and a stereo cable, both of which are working. I have the v 2.4.2[1] update.
I was able to tap tempo with the external FS before and after the update, but now suddenly it will not do it, I initialized and tried the 2 different ways of programming AUX SW (manual and learn) – several times.
I also want to point out that I have never been able to change presets and tap tempo both with an external FS. I have exchanged emails with the good folks at Eventide going back a couple years; nothing I've tried has worked. Too bad, it would be nice to have 2 to 4 tweaked presets to go back and forth between and also be able to sync the delay with the tune.
