- Set [IN1], [CV1] and [RESONANCE] to maximum
- Set [IN2] and [CV2] to minimum
- Set [FREQUENCY] to ‘2’
- Adjust P201 fully counter-clockwise
- Apply a 0.25Hz 5VAC sawtooth to [IN1]
- Monitor the [BP] output
- Apply 0VDC to [CV1]
- Adjust [FREQUENCY] for an output of 10Hz
- Apply 2.0VDC to [CV1]
- Adjust P201 for an output of 40Hz
- Repeat steps (7) to (10) until the desired 4:1 scale is achieved
Note that the adjustment of P201 will affect both measurements so you will need to ‘slowly bring the frequency scaling in to range’ otherwise you could end up chasing your tail!
