Random voltage generation with Qu-Bit’s Chance

With percussion sources, envelopes, oscillators and VCAs, Chance can add humanity to all your patches

We’ll start nice and simple, using the discrete output to add stepped random changes to the decay of an open hi-hat. Take the clock out of Chance to trigger a hi-hat module and then use the discrete output to decay CV for more life.

Sticking with percussion, let’s add some randomly shifting rhythms to our drum beats. Take the rhythm output into a percussion module of choice for shifting rhythms over your beats. Play with the rhythm knob to control the probability of change in the pattern.

We can further explore random rhythms with the burst output, which means that at every clock pulse (or coin toss) a gate burst is generated with a random number of gates, rests and gate lengths. The rate and density of the bursts is determined by the rate knob.

We get two types of noise on Chance: white noise is great for lots of things, but we also get digital noise which has a changing tone. Patch the digital noise into a VCA controlled by an envelope to create shifting percussion sounds.

Patch a pulse wave into a filter then into a VCA controlled by an envelope. Take the smooth output to PWM, filter cut off and decay time on the envelope. Using the onboard ‘attenuverters’ on Chance, you can control the range of movement added to your patches.

The wavetable output offers a continuous tempo-synced LFO. Each clock pulse generates a new random wavetable shape and random division or multiplication of the clock for the LFO rate. Patch the wavetable output to modulate filters, VCAs, waveshapes or FX for random wobbly LFOs.
