The Transient Modules 8S is an 8-step sequencer in 8hp with voltage control over many parameters of the sequence, enabling it to generate deceptively complex patterns from a limited number of steps.

You can input gates into the reset, hold, random step and direction inputs, and this will have a specific effect whilst the gate is “high” (ie: for the length of time the gate is being sustained).

These inputs have been designed to work with clock related signals like triggers or gates but any type of CV signal can be used. There is a transistor acting as a comparator on each input – including the clock input – so you could even clock it from a sine wave. Once a certain voltage threshold has been passed, the input “sees” this as a high (sustained) gate, until the voltage drops below this threshold again. 

All the inputs have been placed on the panel in order of priority. For example, if both RST and RND are both high when a clock is received, the sequence will reset.

Due to the complexity that can be generated by utilising the various gate inputs, the 8S works especially well in a pair, alongside modules such as voltage-controlled switches (for example, the Transient Modules 1F) or random gate generators.


  • RST (Reset) – resets the sequencer to step 1 for duration of gate
  • HOLD – holds the sequencer on the step it is on when the gate is received, until the gate ends.
  • RND (Random Step) – for the duration of the gate, the sequencer will ran through its steps in a random order. While the gate is being held – and the randomness is occurring – the sequencer still “counts” …so it will continue at the correct step once the gate is released. For example – if you triggered a gate at step 4 – and released it after four steps – the sequencer would then continue from step 1 (where it would have been, had the randomness not happened).
  • DIR (Direction) – the sequencer will run in reverse for the duration of the gate


  • The output signal path is completely analog and not quantized.
  • Its range can be set to unipolar (0 to +5 volts) or bipolar (-5 to +5 volts) via a jumper on the back of the module.
