960 sequencer

960 Sequential Controller (moogafakkin System 55 clone — categorized under Ports -> moogafakkin). A 3-row x 8-step analog step sequencer. Each column has a knob per row (24 step pots); on each advance every row outputs its current column value as CV (row1/row2/row3), scaled by that row's RANGE (x1/x2/x4). Steps advance on an external CLOCK input (rising edge) or, when unpatched, an internal RATE clock; CLOCK OUT pulses each advance. Per-column NORMAL/SKIP/STOP switches skip a column or halt the run; START/STOP gate inputs reset/halt. v1; per-step trigger jacks, third-row-controls-timing, x2 parallel outs + 1V/oct clock CV deferred. Own-code (forks the repo sequencer). Beige moogafakkin faceplate (the intrinsic always-on look shared by the moogafakkin module family).

A clean-room recreation of the Moog 960 Sequential Controller — the System 55's analog step sequencer. It's a 3-row × 8-column grid of knobs: a single shared column pointer sweeps the 8 columns (steps), and on each advance every row outputs its current column's knob value as a held control voltage on ROW 1/2/3 OUT. So one pass of the sequence produces three parallel CV streams (e.g. ROW 1 → oscillator pitch, ROW 2 → filter cutoff, ROW 3 → VCA level), all stepping in lockstep. The pointer advances on each rising edge of an external CLOCK, or, when CLOCK is unpatched, at the internal RATE. Per-row RANGE switches scale that row's CV (×1/×2/×4), and a per-COLUMN MODE switch can make a step SKIP (jump past it) or STOP (halt holding that column) for non-linear patterns. A clock pulse is emitted on CLOCK OUT each advance for chaining. It auto-runs on placement. Mental model: three knob-banks read out a column at a time, like three sequencers sharing one playhead. Drive it from a clock (or its own internal rate) and patch the row outputs as stepped modulation/pitch.
