Hi
I don't know how your Zoom works…but regarding Eclipse, TapTempo can be controlled via MIDI CC messages or footswitches connected to Pedal 1/2 inputs, or MIDI Clock.
To patch any source to TapTempo go to SETUP > TEMPO > TAP SRC and set it to Foot Sw1 or 2 if you intend to use any of them or to any Exeternal #, avoiding #1 which is patched to Input Level (Pedal 1) by default. Once you hace choosen an External #, go to SETUP > EXTERNAL > EXT# x (x=the number you have choosen in the previos stage). Here you can select the MIDI CC message sent by your controller to Eclipse to remote Tap Tempo.
have fun
