Description
Inputs (2)
CLK IN
clock
—
Connect an external clock to this input. Each time the Clock input voltage goes high, the sequence advances one step (unless using the built-in clock divider). Steppy will not play without a CLK input.733
RST IN
gate
—
Accepts a trigger or gate. In RESET Mode, resets all patterns to step 1. In RUN Mode, also enables/disables playback (patterns play when gate is high, stop when gate is low).733
Outputs (4)
OUT A
gate
≤5V
Gate output for Track A. Corresponding LED lights when gate is high.733
OUT B
gate
—
Gate output for Track B. Corresponding LED lights when gate is high.733
OUT C
gate
—
Gate output for Track C. Corresponding LED lights when gate is high.733
OUT D
gate
—
Gate output for Track D. Corresponding LED lights when gate is high.733

Type
Range
Behavior
Clock Division
button
1 – 64
Sets the clock division for the selected track. /1 is no division; /64 means the sequence advances one step for every 64 CLK input pulses. Long-press to apply to all four tracks simultaneously.733
Delay
button
0% – 58%
Delays every step in the track by the selected percentage of a clock step. Long-press to apply to all four tracks simultaneously. If combined with Swing, the offsets are summed.733
Gate Length
button
—
Sets gate length for all steps in the selected track. Top button pins gate length to input pulse width; bottom button makes gate last the full width of the step (allowing ties). Middle values yield steadily increasing fixed-length gates. Long-press to apply to all four tracks simultaneously.733
Probability
button
—
Sets the probability that each programmed step will fire. 100% (default) means the pattern plays exactly as programmed. Long-press to apply to all four tracks simultaneously.733
Ratchets
button
1 – 12
Per-step ratcheting: each step can trigger 1, 2, 4, 6, 8, 12, or a random number of gates. Ratcheting automatically sets the step's gate length to 1 tick (a clock pulse divided into 24 ticks).733
Shift
button
-4step – 4step
Rotates the active pattern forward or backward by a specified number of steps (up to 4 in either direction). Long-press to apply to all four tracks simultaneously. Only affects steps within the programmed track length.733
Swing
button
50% – 78%
Sets swing percentage for the selected track. Conforms to MPC 'standard' (plus 78%). Delays every other step. Long-press to apply to all four tracks simultaneously.733
Track Length
button
1step – 64step
Sets the length of the pattern for the selected track (1 to 64 steps). Long-press the desired final step button in Play Mode to set the length.733

Notes
1.20
2020-01-10
Added latching Loopy mode (press SELECT while holding loop buttons to latch). Added delayed preset load (long-press preset button to delay load until end of Track 1 cycle). Added muted tap entry mode (PROB button toggles muting in TAP Recording Mode). Added Step Edit Mode for per-step Gate, Delay, Probability, and Ratchet editing. Fixed Track Probability to apply to current position without randomizing individual ratchets.733
1.11
2019-10-10
Fixed: Additional filtering on Clock input to handle imprecise clock pulses.733
1.10
2019-08-14
Added RUN Mode: sequencer advances only when RST input has a high gate, and also resets when gate goes high. Hold SAVE RST on boot to toggle between RUN and RESET modes. Fixed gate compensation when RST arrives a few milliseconds after clock rise. Fixed manual RST press to immediately reset to step 1 rather than waiting for next clock pulse.733
