Voltage controlled LFO
This is a versatile yet easy to use voltage controlled low frequency oscillator module that can also be used as an audio VCO over a useful range.
The unit features sinusoid, sawtooth, ramp, triangle and square outputs. All are available simultaneously. A sync input is available to reset the waveforms to a fixed point.
The module features two CV inputs. One is fixed at 1V/octave. The other CV input is controlled by a single pot on the front panel. When the pot is turned right of its central position, the pot acts as a normal attenuator; increasing the sensitivity of the CV input to a maximum of 0.5V/octave. Left of centre, the pot will act in inverting mode. Fully anti-clockwise the input will respond to -0.5V/octave.
A tricolour LED indicates the output status.
The VC-LFO has an operating range of lower than one cycle every 5 minutes to over 7 kHz from the front panel controls.
The range can be extended with external CV inputs. The maximum frequency of the VC-LFO is well over 25kHz.
When used as an audio rate VCO the usable range that conforms to 1V/octave (to +/-2cents) is over six octaves from approximately 32Hz to 2kHz. This is none too shabby for a low frequency oscillator. For accurate musical use over 2kHz we recommend that you use the Oakley VCO.
Sync input requires a fast rising gate exceeding 4V when active, or at least 2V peak pulse or sawtooth waveform.
Available as an assembled Module and as a DIY project.
