CALIBRATION
OSCILLATOR SCALE
Oscillator 1:
1. Connect MIDI keyboard to synthesizer (MIDI IN).
2. Set oscillator 1 and 2 to sawtooth waveform.
3. Set the LPF MIXER control knobs on oscillator 1 and 2 to position 8, and all other control
knobs to position 0.
4. Set LPF CUTOFF control knob to position 10
5. Set AMP FILTER MIXER control knob to position LPF.
6. On MASTER CV set switch for OSC2 to off.
7. On OSC 1 set RANGE and TUNE to position 0.
8. On OSC 2 or OSC 3 set RANGE switch to position 1, and TUNE to position 0 for 5 octave
keyboard or position 0 for 8 octave keyboard (Master keyboard).
9.
both oscillators have the same frequency and minimum phase shift.
10.
Press each successively higher C (C3, C4, C5, etc.). Adjust trim potentiometer OSC1, SCALE
on the rear panel for correct frequency. The frequency of Oscillator 1 must correspond to C3,
C4, C5, etc. When correctly adjusted the Oscillator 1 frequency is exactly 2, 4, 8, 16…etc.
times higher than Oscillator 2.
Press the lowest C on the keyboard and adjust FINE TUNE on the MASTER CONTROLLER until
24
