Tube overdrive / VCA with built-in filtered feedback path.

  • Miniature vacuum tube
  • IN/OVERDRIVE : drive the tube (white pot)
  • FEEDBACK : reinjection level
  • FB COLOR : low pass filter for feedback path
  • GAIN CV : tube gain control
  • FEEDBACK : second signal input. Output of the filter (color) is normalled to this input. This allow to bypass the filter in the feedback loop.

SIZE: 3HP – 39 mm deep (including inserted power connector)
+12V : 9 mA
-12V : 18 mA
+5V : 0 mA

WARNING: This module picks up alot of the power supply noise (due to the tube design). It is not intended as “HIFI” use. The frequency response of the design is (intentionally) not limited, and the tube may rings with a high tone for some seconds when it receives mecanical vibrations (jack insertion for example). This is a common microphonic phenomenon.


Gate probability with memory.

This module allows to control the probability to pass incoming gate signals at the output.
The resulting sequence can be “freezed” and stored in 5 memories.

  • SEQ# : selects memory to play (white pot).
  • REPLAY / FREEZE sequence
  • LENGTH : sequence length
  • OODS : probability to pass gate at the output
  • CV input for ODDS / SEQ# / FREEZE

SIZE: 4HP – 38 mm deep (including inserted power connector)
+12V : 12 mA
-12V : 0 mA
+5V : 0 mA

Noise Pattern Generator

This is a Eurorack version of A01 (Glitch and Noise Generator). All parameters are now open to modular world.
Extra feature: time delay can be synced.


  • 14 HP eurorack module (35 mm deep)
  • PT2396 used as noise core
  • Pattern duration can be synced with pulses (sync in) or with tap button
  • divide / multiply sync input
  • built-in frequency divider
  • built-in oscillator for the ring modulator, input for external oscillator
  • built-in VCA with dedicated output
  • modulation inputs: TIME A, OCTAVE
  • trigger inputs: EG, RESET, TIME B, CHAOS1, CHAOS2
  • power consumption: 40 mA +12V, 4 mA -12V

Brick Sequencer

This is a 16 steps trigger sequencer working with LEGO bricks. Jam with kids! Customize the look with your favorite lego tiles! Check demo video!


  • 34 HP Eurorack module (22 mm deep).
  • 4 rows/channels
  • 4 mutes buttons
  • in and out points on bottom row
  • 16 memories to store patterns
  • clock input
  • reset input / reset button
  • working with 1×1 LEGO bricks
  • power consumption: 30 mA +12V, 0mA -12V

Although the stud detection algorithm is quite strong, this is working with light so: flashing lights or low light environnement will produce unexpected results. No real LEGO were harmed to build this: the machined base plate is a chinese copy 😉
