We are happy to welcome Spanish brand Transient Modules into our fold, kicking off with 3 of their modules which all offer something quite unique, and also extremely useful – 4R (Quad Random Voltage), 8S (8-Step Sequencer) & 1F (Voltage Controlled Switch). At first glance they might seem simple & utilitarian, but dig a little deeper and some excellent finishing touches give these the edge over many competitors. Full details on the relevant product pages.


  • 4R – Space-saving quad random voltage generator, featuring: 2 independent trigger inputs; normalising between trigger inputs; 2 pairs of random voltage outputs; each pair can be set to be either unipolar or bipolar (via jumpers)
  • 8S – Deceptively powerful 8 step sequencer with voltage control over reset, hold, random step & direction. Output can be set to unipolar or bipolar via a jumper.
  • 1F – Voltage controlled switch, designed with a focus on working with sequences – by giving them some randomness, applying transpositions or constant variation over time. You can take 2 input signals and switch between them upon receipt of a gate. You can also switch between one signal and the SUM of both signals …and you can also manually bypass the switching completely.
