Itijik Toggle — Cheat Sheet

What it is

A quad flip-flop / logic utility for Eurorack.
It gives you 4 identical sections, each with: - SET - RST - CLK - IN - OUT - VERT

Core idea: - OUT is the flip-flop output. - VERT is the inverted output unless you patch something into IN, which breaks that normalization.

Power / Installation

+12V: 37 mA
-12V: 34 mA
10-pin ribbon on module: red stripe to -12V (bottom of module)
16-pin ribbon on bus board: red stripe to negative side

How each section works

Each of the 4 sections is identical.

Basic behavior

Send a pulse/gate to SET → OUT goes HIGH
Send a pulse/gate to RST → OUT goes LOW
Send a pulse/gate to CLK → OUT toggles
If IN is unpatched, VERT = inverse of OUT

IN jack behavior

Patching IN breaks the normal connection from OUT to IN
VERT becomes the inversion of the IN signal instead of OUT
So:
IN HIGH → VERT LOW
IN LOW or no signal present at IN → VERT HIGH

Fast patch ideas

Clock divider by 2 / toggle gate
Patch a trigger stream to CLK
Take output from OUT
Each pulse flips the state
Manual state logic source
Use SET and RST from two different trigger sources
Great for rhythmic state changes
Complementary gates
Leave IN unpatched
Take OUT and VERT as opposite logic signals
Standalone inverter
Patch a gate into IN
Take inverted gate from VERT

Jack Reference

Inputs per section

Jack	Function	Notes	Voltage Range
SET	Forces OUT HIGH on received pulse/gate	Also forces VERT LOW if IN is unpatched	Not specified in manual
RST	Forces OUT LOW on received pulse/gate	Also forces VERT HIGH if IN is unpatched	Not specified in manual
CLK	Toggles OUT on each received pulse/gate	Also toggles VERT if IN is unpatched	Not specified in manual
IN	Logic input for inverter	Breaks normalization from OUT to IN when patched	Not specified in manual

Outputs per section

Jack	Function	Notes	Voltage Range
OUT	Main flip-flop output	Normalized to IN for inversion when IN is unpatched	Not specified in manual
VERT	Inverted logic output	Inverts OUT if IN unpatched; otherwise inverts IN	Not specified in manual

Controls / Indicators

Controls

No knobs
No buttons
No sliders
No toggle switches

Indicators

LEDs for OUT and VERT on each section to show logic state

Important normalization

No cable in IN:
VERT = NOT(OUT)
Cable in IN:
VERT = NOT(IN)
and the OUT-to-IN normalization is disconnected

Good to know

The manual does not specify exact logic voltage thresholds or output voltage levels, so treat all pulse/gate voltages as unspecified by manufacturer in this document.
