KNOB: OSCILLATOR 2 FREQUENCY
Engage Shift mode and turn Oscillator 2’s FREQUENCY knob to set the “Beat Frequency” of Oscillator 2 against Oscillator 1.
The range is plus or minus 3.5 Hz, with no detuning (0Hz) in the middle. This parameter creates a linear constant detuning of Oscillator 2 relative to Oscillator 1, so that Oscillator 2 is always detuned by the same number of cycles per second (Hz) regardless of the musical pitch. The result is a musical detuning effect which phases or “beats” at a consistent rate on every note.
By contrast, the OSCILLATOR 2 FREQUENCY knob detunes Oscillator 2 by musical cents, where the rate of beating between Oscillators is halved or doubled as you play an octave lower or higher in pitch.
NOTE: For this reason, if you want a constant beat frequency at all pitches, make sure that the regular OSCILLATOR 2 FREQUENCY control is centered. If you want absolute unison between Oscillator 2 and Oscillator 1, make sure this BEAT FREQUENCY control is centered.
