Cycling Random Voltage Generator

DriftLog is a dual-channel Cycling Random Voltage Generator built around controlled, loopable randomness, in a 12HP footprint. It generates, captures, and reshapes random voltages in real time, turning randomness into a flexible, repeatable, and playable modulation source.
Each channel generates its own independent random voltage while sharing a set of motion-shaping controls. Slope morphs the output from sharp, stepped jumps between values into smooth, continuous glides, while Shape sculpts the curvature of those glides, from linear transitions to Bezier, exponential, and peak-based curves. A shared Clock sets the rate of new values, and Prob introduces controlled variation in whether a change happens on a given step. Individual Lock buttons let each channel hold its own Slope, Shape, and Prob settings, so contrasting motion behaviors can run on both channels at once using the same shared controls.
Each channel continuously records its recent random history and can be switched into Loop mode to replay a selected portion of it. Start and Length, adjustable live during playback, define the loop range, turning free-running randomness into repeatable modulation patterns while keeping its organic character.
A single Shift layer adds access to secondary functions, all clearly labeled in gold on the panel: DC Offset, Swing, Manual Reset, and Gate/Trigger selection. Holding Shift for three seconds saves the current settings, recalled automatically on power-up.
