One of our all time favorites at Midwest Modular!  A super unique way of creating regular and generative rhythms, guaranteed to produce different results than your typical trigger sequencer!

A matrix of flexible clock dividers that are OR logic combined to create complex rhythms-this gate sequencer is a riot to play! Effortlessly create unexpected results with this new paradigm of gate sequencing.


  • Powerful 28hp Eurorack sequencer module based on clock divisions
  • 4 x 4 encoder grid lets you create complex sequences by stacking clock divisions
  • Clock divisions are combined via OR logic, which only picks the highest voltage among the clocks, which allows long gates to block out other clock counters
  • Matrix mode and Independent mode provide 2 approaches to sequencing
  • Add probability to each clock division to create an organic, random effect
  • Get creative with Speed, Clock Shift, Time Shift, and Pulse Width settings for each step
  • Each of the 8 outputs includes a dedicated mute switch for live performance
  • External sync (including DIN sync) provides integration into complex synth rigs

Since each of the 16 knobs represents a real time tweakable trigger generator/modifier the Trigger Riot is extremely playable and can result very complex patterns with only few knob turns; patterns that would otherwise take much longer and in some instances be almost impossible to produce using grid based step sequencing. Patterns can have unique time signatures that can repeat or be randomized through probability, time shifted and phased, divided, multiplied and counted, it’s unbelievable how complex this module can get with minimal input.

Clock Functions include:

  • Divide: Divide the clock stream into either even or odd divisions from 1 to 255.
  • Speed: Multiply or Divide the clock streams in sub clock particles based on 24 PPQ, breaking up the standard grid values.
  • Probability: Sets the odds of a trigger firing which makes more varied and less rigid patterns or can create subtle accents and fills.
  • Pulse Width: Sets the pulse width of each stream, creating overlaps and as a result all kind of odd time signatures; also great for sustaining envelopes or for programming a high pulse fro some time.
  • Clock Offset: Moves the trigger streams in time to change the relationship between streams. Streams can be set to the same amount but offset to trigger in between each other rather than simultaneously to create syncopation effects.
  • Time Shift: Shifts the triggers streams variably in between clocks for swing type feels and off the grid patterns.
  • Step: Places single shot triggers on individual clock ‘Steps’ to trigger events once per pattern. This can also be seen as a pulse counter.
  • Mute/Sel: Muting of each trigger output for live dub mixing or to select which row to edit in ‘Independent’ mode.
  • Tap tempo: Tap in your own time.
  • Cycle: Internal reset counter to constrain pattern length and relationships between divisions.
  • Clock Out: Trigger out of the Riot’s highly accurate internal clock.
  • Clock Input: External clock.
  • Reset Out: Trigger output based on the internal reset length.
  • Reset In: External trigger input to reset the internal count.
