7. Tap Tempo and BPM
BIAS Modulation comes with a Tap Tempo footswitch that allows you to quickly set the BPM
value that controls the LFO rate. The elapsed time between two taps represents a beat (¼
note) and determines the BPM (beats-per-minute) value.
For example, when you tap twice in 0.5 sec :
2 taps in 0.5sec = 1 beat in 0.5 sec = 120 beats in 60 sec = 120 BPM
After producing a BPM value using Tap Tempo, you can still adjust the RATE knob to change
the note subdivision, to speed up or slow down the LFO rate. Set the RATE knob to the 12
o’clock position for a quarter note value.
6. LFO
The LFO (Low Frequency Oscillator) generates a very low frequency (below 20Hz) that
modulates signal phase to create a modulation effect. Each type of LFO waveform produces
unique characteristic in the resulting sound.
Built-in waveform types for BIAS Modulation:
・ Round
・ Triangle
・ Pulse
