Range of the LP Filter
Connect a well calibrated V/Oct Source to the LPF
CV
input. Set the HPF
potentiometer fully counterclockwise. Set the RES potentiometer fully
clockwise. Activate the LPF resonance switch by pushing it toward the right.
The HPF resonance switch must be off and the LPF potentiometer at noon.
The LP1 trimmer on the diagram below, sets the range of the first lowpass
filter. Listen to OUT 1, you should hear the filter auto-oscillate. Play on 3
octaves with your V/Oct Source. While playing on 3 octaves, adjust the LP1
trimmer until the interval you hear is as close as possible to 1 octave between
each note. Do the same procedure using OUT 2 and the LP2 trimmer.
