Well, here I am, ridiculously, 10 months later, still trying to figure out a way to tap in a tempo live while not having the VoiveLive Rack right next to me or needing a free hand to push the physical tap tempo button. I'm shocked that tap tempo isn't assignable to the Switch 3, so I'm trying to use a Line 6 HDX Pod Pro X, which allows me to tap a tempo in via footswicth, as a tempo source for the Voicelive Rack. I've set the midi channels on both devices to 1, I have set the Delay source on the VoiceLive Rack to midi, and still... nothing. Has anyone found a way to change the Tap Tempo dynamically on the VoiceLive Rack? I think what I'm trying to accomplish here is super basic, and I'm getting frustrated as I hit brick wall after brick wall.
