Random Walks

This module provides 2 channels that produce voltage values following a random walk (Brownian motion), but sharing the same randomness parameters. There are controls for the range of the walks, the offset on the range, the step size, and the glide time between values. All of these parameters are CV controllable. The two channels can be clocked together by selecting the normal trigger toggle (1>2), or they can be clocked individually, and there is also a switch to select between a fixed step size, or steps that go up to the selected step size. There are also reset buttons and inputs, which send the next triggered value to the center of the range.

Notice that the offset is applied to the range, and not to the produced values, so changing the offset may not immediately affect the output values (as the walk could still be inside the selected range). But the walks can be reset after changing the range and/or offset values, and they will immediately jump to the center of the new range.

The Trc toggle (trace) on each channel turns on a meter that keeps track of the output values, for visual reference. It is off by default to save processing power, and it is recommended to turn it on only temporarily when wanting to inspect the output values of the walk.

Random Walks is really useful for producing random melodies and arpeggios, adding controlled randomness to any parameter, and for modulations that are not repetitive but are instead constantly changing. It is a great tool for generative music and improvisation!
