There are many fantastic modules in music making; common ones being filters, oscillators, and envelopes but there are a world of other options. This Voltage Controlled 4046 Wave Shaper is one such example, which takes an input oscillation from an external VCO (Voltage Controlled Oscillator) and allows you to output that one single sound over multiple octaves!
The design is based on the Barton Musical Circuits 4046 Wave Shaper, which uses a uses a CD4046 phase locked loop chip in combination with a binary counter to multiply the frequency of the input signal – allowing for a vast range of output frequencies between -3 Octaves and +3 Octaves. This particular design uses a Voltage Controlled mixer, which enables you to send it CV signals to modulate the played back sounds. It also has a gain control for the output signal, which is a convenient addition for when the signal gets a bit hot.
Note that in order to complete this build you’ll need to source some extras detailed on the product page. The Voltage Controlled 4046 Wave Shaper is sold by Analog Output who are based in Syracuse, NY in the USA – and offer a wealth of modular goodies to check out! See the Wave Shaper in action below:
