Bastl Dynamo Utility Module

Dynamo by Bastl Instruments is a three-section utility module comprised of an envelope follower, comparator, and voltage-controlled switch. The module extracts gates from envelopes using a combination of its first two sections, with the option to send the signal through a full-wave rectifier. There’s also an onboard compressor just waiting to be routed to the CV input of any external VCA or VCF!

The module is also capable of pseudo-thru-zero modulation under: simply use the full-wave rectifier in combination with the comparator and controlled switch. Best of all, Dynamo ensures this effect is able to be manipulated remotely via CV. 

Dynamo Utility Module Features

  • 5HP
  • Two passively connected Envelope Follower inputs (multiple)
  • Inverted and non-inverted Envelope Follower Output
  • Full-wave Rectifier Output |EF IN|
  • Compressor CV Output with indication LED (only negative voltage when envelope is greater than the threshold)
  • THR-EF output is similar to compressor CV but can go to positive voltages – it tilts the whole Compressor dynamics curve (not only the part above threshold)
  • Selectable Envelope Follower Release time (Short, Mid, Long)
  • Output of Envelope Follower is normalised to Comparator Input
  • Comparator with Threshold knob, Threshold CV, Input and Output
  • Output of Comparator is normalised to the Gate of VCS
  • Voltage Controllable Switch is bi-directional (non-buffered) A or B switch
  • VCS Gate threshold is around 1.5 volts
  • On high gate the B signal is connected with A or B connector (otherwise it is A)
  • Signal on A is inverted and normalized to B (easily achieve bi-polar VCA emulation or other waveshaping)
