Inputs

Jack	Function	Voltage Range
a	Main gate/trigger or clock input	0-5V or 0-10V (typical)
m	Hidden Reset input (in certain modes)	0-5V or 0-10V (typical)

Note: The specified voltage range isn't detailed in the manual. Generally, 0-5V triggers/gates are expected for this type of module.

Outputs

Jack	Function (depends on mode)	Output Voltage
b, c, d	Main gate/trigger outputs (random or divided clock)	0-5V (typical)
e, f, g	Sub-outputs for main output b	0-5V (typical)
h, i, j	Sub-outputs for main output c	0-5V (typical)
k, l, m	Sub-outputs for main output d	0-5V (typical)

Random/Pattern Mode: Trigger signals routed randomly or via patterns to these outputs.
Clock Divider Modes: Each output carries clock divisions as per chosen divider mode.

Controls

Control	Type	Description
n	Rotary knob	Interpolates between fully random and 16-step repeating patterns. Used with o to select modes.
o	Button	Tap for new random sequence. Hold + Turn n to select mode; hold on power up for debug mode.

Operation & Modes

Basic Gate/Trigger Routing

Send a trigger/gate to input a.
The module randomly routes to one (or more, in poly modes) of b, c, or d, then randomly to one of their 3 sub-outputs.

Mode Selection (while power is on)

Hold o (Freeze button)
Turn rotary knob n
Visual pattern (via LEDs) shows selected mode:
Mono/Mono: Random single path
Poly/Mono: Randomly to one or more main outs, each to one sub
Poly/Poly: Random polyphonic through all outs
Latch modes: As above, but output is held until new input/clock

Randomness vs. Pattern

Turn n: Left = fully random, Right = repeating 16-step pattern
Tap o: Generate a new random sequence.

Clock Divider Modes (selected by turning o knob in main mode)

Position of o	Mode	Output Assignments
Fully left	Classic Divider	b: /2, e: /4, f: /8, g: /16. c-h-m: 8-step sequencer.
Center	2/3/5 Divider	b-e-f-g: /2,4,8,16; c-h-i-j: /3,6,12,24; d-k-l-m: /5,10,20,40
Fully right	Spread	Successive integer divisions: /2, /3, /4, /5, /6, /7, ...

Reset & Debug

Auto-reset: If input pauses, resets to first step.
Hidden Reset Input: m jack can act as a reset in loop mode; enable in debug mode.
Debug Mode: Hold o on power-up; outputs & LEDs will cycle for testing.

Quick Mode/Modes Reference

Mono/Mono: Random single path b/c/d → e-g/h-j/k-m
Poly/Mono: Randomly to several b/c/d, each picks one sub-out
Poly/Poly: Poly trigger through all main + sub-outs
Latch variants: Out is held till next gate/trigger
Clock Divider: See divider modes above

General Tips: - Modes are visually indicated via LEDs for intuitive feedback. - Combines random logic, clock dividing, and switch routing in one compact module. - Excellent for generative rhythms, randomized sequence distribution, or complex clocking.
