A-160-2

Doepfer 4HP

Clock/trigger divider with 7 outputs and three switchable divisor sets: powers of two, primes, or integers. Two output modes — Gate (50% binary) and Trigger (AND'd with clock, inherits its pulsewidth). Jumper-selectable clock edge, reset polarity, output polarity.

Behaviors

Binary bar/beat divisions POW2 mode

Standard powers-of-two divisions produce musical bar, half, quarter, eighth relationships when clock is a 16th or 32nd. Ideal for song-structure gates.

Prime-number polyrhythms PRIME mode

Divisors share no common factors, so outputs drift apart maximally. ÷11 and ÷13 only re-align every 143 clocks, yielding long, non-repeating rhythmic textures.

Odd-meter integer grid INT mode

Sequential integer divides give triplet, quintuplet, septuplet relationships useful for odd-meter patterns that still resolve periodically.

Trigger mode pulsewidth masking Output Mode: Trigger

Outputs are AND'd with the raw clock, so each divided pulse takes the clock's pulsewidth rather than a 50% gate. Useful for drum-style triggers that sit inside the clock phase instead of stretching across it.

Synchronous reset on bar boundary bar-length pulse → Reset In

A reset pulse per bar realigns every output to phase 0, preventing drift when the divider is re-entered mid-song or when the clock is stopped/started.

Hardware-configured polarity internal jumpers

Clock edge, output polarity, reset level vs edge, and reset polarity are all jumper-selectable on the PCB — no front-panel way to change. Relevant when interfacing non-Doepfer gate standards.

Controls

Divisor set Division Mode 3-position switch picks which divisor set the seven outputs use.

  • Clock In digital / gate GATE
    Digital clock/trigger input. Accepts any pulse source — LFO square, MIDI-sync gate, sequencer trigger.
  • Reset In digital / gate GATE
    Synchronously resets all divider counters. Level or edge mode and polarity are jumper-selected.
