F2
Coarse manual control of frequency F2. Range is ≈ 8 octaves.
F1 fine tuning
for frequency F1. Range is ≈ two half notes.
Frequency range selector The value of the oscillator's timing capacitor, which is working for
both FSK frequencies, can be changed by this switch. 3 different ranges are provided:
1. Lo (switch in left position) for LFO applications and/or tremolo-like sounds
2. Mid (switch in middle position) for bass or sub-bass sounds
3. Hi (switch in right position) for mid-range and high audio frequencies
Because the frequency CV-ins of the internal VCO chip are not linear over the entire audio
range, it is recommended to use the 'Mid' position for bass sounds and the 'Hi' mode for higher
frequencies (although it is possible to produce low frequencies in the 'Hi' mode too). This
ensures better 1V/oct. tracking in the lower frequency regions.
F2 fine tuning for frequency F2. Range is ≈ two half notes.
