Oscillator Tuning Procedure

  1. Balance the Micromoog on its nose so the rear panel is up with controls facing you.
  2. Connect to amplifier, turn on, and warm up for 10 minutes.
  3. Oscillator Range: Set Oscillator to Drone, Octave to 2', Fine Tune to Vertical. Compare pitch to F above high C (700Hz). If Fine Tune requires significant movement from vertical, adjust the OSC RANGE trimpot.
  4. Oscillator Scale: Depress and hold LO F. Zero beat with reference 2 octaves below using Fine Tune. Depress and hold HI F and adjust OSC SCALE trimpot for zero beat.
  5. Oscillator High Frequency: Depress LO F and zero beat with F5 (700Hz). Depress HI F and adjust OSC HI trimpot for zero beat. Repeat steps 4 and 5.
  6. Oscillator Octave Step: Depress LO F and zero beat with F5 using Fine Tune. Set Octave to 16' and adjust OSC OCT trimpot for zero beats.
