Detroit Underground - DU-Seq

Overview

This sequencer has an all-analog path and features a maximum number of eight stages, for each a number of parameters can be set: 2 octave pitch, slide, six different gate options like number of repetitions and external gating. A buttom and a gate input meke the sequencer run in half speed. Besides that the sequencer has a clock, step addressing or reversible playback direction.
the concept with pitch sliders and repetition function might look familiar another sequencer but the DU-Seq stands out being entirely analog with discrete logic used for gating - no microcontrollers here!

Details

The sequencer can be synchronized to an external clock but a clock generator with clock output is integrated as well. The gate lenght of the clock pulses is determines with the Gate Time potentiometer.
When a gate is present at the 1/2 CLK input or the according button is pressed the sequencer will run in half speed. DIR/ADD has a dual function - in Direction mode a high gate makes the sequencer run backwards. In Addressing mode you can addrss the steps with a control voltage. The Stage Count rotary adjusts sets the length of the sequence, from one to eight steps.

The CV for each step is set with the faders which have a range of two Volts, i.e. two octaves. The LEDs visualize the gating.

Behaviour for each step is set with the bottom section:
The Slew buttons activate a glide fro mthe prevoius to the selected step.
The white controller selects the gating behavoiur. From top to bottom there are following six options:

  • Exernal Gate 1: reads out the upper EXT GATE input.
  • Exernal Gate 2: reads out the bottom EXT GATE input.
  • long gate: one single long gate is played.
  • multiple gate: a number of shoerter gates is played and thus the step is repeated up to eight times. The black control sets number of repetitions.
  • single gate: this one is as long as determined by the Gate Time control.
  • no gate: at this step no gate is emitted but a CV still will be.
