Description

VCO based on the CEM3340 chip.

The 1222 Performance VCO is Look Mum No Computer's first Oscillator PCB Design. Born from frustration of playing shows, or not having a tuner to hand and getting in tune enough to get going, instead of sitting around being out of tune. Its also got an octave knob. a fine tune knob that is exactly an octave with a centre point of C making it easy to find the note you need. Big simple controls, pulse width, PWM, fine tune, Extra CV, Sync, FM, Square, Ramp and Triangle outputs. It also has a rear connection called LINK, which will be for future use, as i will be making an oscillator drive a nice means of driving lots of oscillators at once, as well as a mixer module so no need to patch all of the oscillators together they will be connected from the back. A final design is like a cross mod module that will turn them into a sort of fart box thing. This is all future ideas, but if you cant wait check the schematic it will make sense!

Features:

  • Octave Switch adds 0-4 volts—or 5
    octaves—to the 1v/oct signal.
  • Fine Tune has a one octave range.
  • Tuner shows the nearest note and
    LEDs indicate wether it’s flat (left),
    sharp (right) or bang on (middle).
  • Pulse Width can be adjusted from
    0-50%.
  • Additional Frequency CV input and
    attenuator.
  • Pulse Width Modulation CV input
    and attenuator.
  • Frequency Sync input. Works best
    with simple waveforms.
  • Frequency Modulation CV input.
  • Simultaneous Pulse, Ramp and
    Triangle outputs. Note that the outputs
    are unipolar audio signals with levels
    that vary from +4v to +8V
