VCO with AM and FSK (Frequency Shift Keying)

The XR22 VCO FT is a modified version of the previous model XR22 VCO with a different manual frequency control.
Instead of the two ±2-octave switches and the two frequency knobs (ca 4-octave range), there are now two frequency knobs (ca 7-octave range) for coarse tuning and 2 fine tuning knobs. Further, the ‘Low F’ frequency range switch – which works for both FSK frequencies – is replaced by a 3-position shift switch with the settings ‘Lo’ (for LFO/ tremolo applications), ‘Mid’ (for bass sounds) and ‘Hi’ (for normal/high frequency sounds).
