WMD Volt Precision Voltage Source & Offset Generator Now Available

WMD has released the VOLT – a precision voltage source and offset generator for Eurorack modular synthesizers.

The VOLT can be used to calibrate oscillators, filter tracking, or anything that needs accurate 1V/Oct calibration.

VOLT has two buttons.  Push the top to increase the voltage by one volt.  Push the bottom button to decrease the voltage by one volt.  Push both buttons at once to reset the voltage back to a known value.

VOLT has 3 voltage inputs and 3 voltage outputs.  The input signal is summed with the voltage source, generating offsets of 1V or 1 octave at a time.  This means it can be used as a precision octave switch for oscillators that lack the functionality.  Create variation in your sequences with a quick touch of a button.

VOLT’s octave buttons can also be switched via external gates, essentially making it an octave sequencer. One input causes it to go up, and the other causes it to go down.  Two gates at once will reset the voltage back to your set value.


  • VOLT is extremely precise, with an offset error of +-1mV and a gain error of 0.033%.
  • 14V range
  • 3 in / 3 out precision adding
  • Gate inputs for sequence octaves with external CV
  • User set-able reset point for more control

Pricing and Availability

The VOLT is available now for US $179.

  1. Nice module and good price.
    Wished I had one 20 years ago when I was tuning and adjusting Moog synths combined with an early days Midi to CV box for live performance by ear using a piano as reference.
