Behaviors

Active clock multiple patching multiple destinations from the three F outputs

Unlike a passive mult, MuDi buffers every output. Patching and unpatching cables on the fly does not disturb the timing at other outputs — clocks stay locked while you reroute the system.

Trigger conditioner weak or non-square pulse at CLK input

The internal comparator fires on any signal crossing 2V and emits a clean 10V pulse at every output. Use MuDi to rescue low-voltage drum-machine clicks, MIDI-clock LFO pulses or rounded LFO peaks into rack-clean clocks.

Binary divider chain pulse stream at CLK

Divisions are a flip-flop cascade — 1/2, 1/4, 1/8, 1/16 — each toggling on the rising edge of the one above. Duty cycle at each division is 50% regardless of the input duty cycle.

Reset via TRS ring rising edge on the ring contact of the CLK/RST jack

Resets the divider chain to its initial state so all divisions align with the next clock. Supplied splitter cable breaks out a second 3.5mm jack (red) for the reset. With a mono cable the reset is grounded and never fires.

Audio-rate suboctaves square-wave VCO patched into CLK

Because the divider is logic-fast, a square at audio rate produces −1, −2, −3, −4 octave suboctaves at the division outs. The F outs pass the original square through the conditioner — useful as a hard-edged squarer before a mixer.

Controls

Global (no panel controls) MuDi has no knobs, switches or buttons. Behaviour is fully determined by the incoming clock and reset.
all logic is firmware-free active buffering + divide-by-2 chain

I/O

IN · 1

  • CLK/RST >2V trigger threshold (tip) · rising-edge reset (ring) GATE
    TRS combo jack. Tip carries the clock; ring carries reset. With a mono cable only the clock side is used. Any pulse above 2V is accepted and conditioned; audio-rate square waves produce suboctaves on the division outs.
    NORM → reset line tied low when mono cable is used

OUT · 5

  • F (×3) 0V / +10V pulse GATE
    Three buffered conditioned copies of the input at the same frequency, each rescaled to a clean 10V pulse. Active topology — hot-patching does not drop the master clock.
  • 1/2F 0V / +10V pulse GATE
    Half the input frequency. Toggles every rising edge of CLK.
  • 1/4F 0V / +10V pulse GATE
    Quarter the input frequency.
  • 1/8F 0V / +10V pulse GATE
    One eighth the input frequency.
  • 1/16F 0V / +10V pulse GATE
    One sixteenth the input frequency. Good for long bar-level pulses or slow triggers.
