The SLOW/FAST, TAP TEMPO footswitch has 2 functions: 

1) 

TAP TEMPO (works only with the MODE button in “up”-position) enables you to tap 

 

the modulation speed while playing

2) 

SLOW FAST (works only with the MODE button in “down”-position) lets you increase 

 

or decrease the modulation speed fluently, -exactly like a real Leslie rotor. Press the 

 

footswitch and the speed will slowly increase to the setting of the SPEED knob, press the 

 

footswitch again and the speed will decrease to the slowest speed of the pedal.  

The MIDI button controls whether the pedals should react on a MIDI signal (via the MIDI socket 
on the side of the pedal), or the pedal should react on manual settings on the SPEED knob and 
the SLOW/FAST, TAP TEMPO switch:

- In “up” position the BetaVibe acts as a typical floor pedal. Knobs and footswitches can be used
- In “down” position you can only via MIDI control following parameters:

1) 

TAP TEMPO (CTL. No. 22)

2) 

SPEED EXPRESSION PEDAL (CTL. No. 01)

In “down” position the SPEED knob and the SLOW/FAST, TAP TEMPO footswitch is deactivated. 
The modulation speed is only controllable via MIDI.

3) 

ON/OFF (BYPASS) (CTL. No. 23)
