Tap Tempo And Bpm; Expression Pedal; Calibration - Positive Grid BIAS MODULATION TWIN Product Manual

6. Tap Tempo and BPM

BIAS Modulation Twin comes with a Tap Tempo footswitch that allows you to quickly deter-
mine the BPM value to control LFO rate. Two taps represent a beat (¼ note) and the duration
of two taps (beats) decides the *BPM value.
For example, when tap twice for 0.5 sec
2 tap / 0.5sec = a beat / 0.5 sec = 120 beats / 60 sec = 120 BPM
After deciding a BPM value with Tap Tempo, you can still tweak RATE knob to change the
note subdivision to speed up or slow down LFO rate. Turn RATE knob to 12 o'clock for ¼ note.
