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.
