The Random Looping Sequencer provides a clockable source of randomly changing voltages via a 16 bit shift register. It’s most obvious use is as a pitch sequencer for an oscillator. Run the RLS through a quantizer to create continuous tempered generative music or lock in a repeating sequence or 8, 16, or 32 notes.
Due to the wide range of output voltage (0-10v), the RLS can also be used for modulating almost anything in a modular synthesizer: VCF cutoff, VCA amplitude, EG triggering, or neural computer summing and offset. You can even use the RLS as a wave shaper by clocking it at audio rates. The acRLS also has a CV input for controlling randomness with an external source.
A bonus feature is an analog white noise output that can be used in all the wonderful ways that one uses noise in a modular environment. This circuit was designed by Tom Whitwell and is graciously available to us via a creative commons license.
The sequencer uses a clock input to cycle through a series of voltage outputs, from 8 to 32 steps, which can be captured in a specific pattern if desired. The range of cv output is also adjustable.
The acRLS is being clocked by a Modcan 05B and is controlling the pitch of a Modcan 01B VCO.
