Voltage Research Lab Loopop Review

Review and tutorial – VRL (Voltage Research Lab) from Pittsburgh Modular

Voltage Research Lab is now in production and Pittsburgh Modular had a spare prototype to send in for review. VRL is their Buchla-inspired mini synth with a primary complex oscillator that has a unique take at waveshaping and folding, an emulation of the classic low pass gate response and more. Here’s my review of VRL along with detailed scope analysis of the various waveshapers and dynamics features (response and pluck):

  1. One issue is there is no output for CV coming from MIDI. Without CV out, we need to have an other MIDI module if VRL is used in a more complex modular system. A bit of a shame.
