Sujet Tap Tempo DIY pour vibe machine

Any latching or momentary footswitch wired between sleeve and tip should work well. In case of a momentary switch, in order to work with the Vibe Machine, it needs to be "normally open", not "normally closed".

To get your Vibe Machine ready for the use with an external footswitch, you should activate one of the 3 modes for that (S4, S5, S6). By default, pedal is set to E1 mode which is the mode for an expression pedal usage, so keep that in mind

S4 External footswitch - Cancel function only
S5 External footswitch - Cancel function and Tap tempo function
S6 External footswitch - FAST/SLOW function with Leslie ramp delay; Two speed switch
