      The Dual EnvVCA is a two-channel analog linear envelope generator with two fully independent low-noise exponential VCAs. With time ranges from 30 minutes to 8kHz, it can be used as an LFO, slew limiter, ASR/ADSR complex EG, audio-rate oscillator, stereo audio/CV VCA, envelope follower, sidechain processor, and general utility module. The outputs can be attenuated, inverted, and offset without disrupting the VCA, making it a versatile modulation source.

      100% analog

      Dual EnvVCA features:

      • Versatile linear envelope generator/LFO
      • Low-noise, low-distortion, DC-coupled exponential VCAs
      • 100% analog
      • Sliders and Range switches control Rise and Fall times from ~1.25ms to ~5 min.
      • Time CV jack extends time range: ~125µs (8kHz) to ~30 min.
      • Independent attenuverters for Rise and Fall time
      • Blue/Red LEDs indicate strength and polarity
      • Cycle buttons for looping envelopes (LFO)
      • Trigger input jacks fire a one-shot envelope
      • Cycle gate input jack toggles cycling for both channels
      • EOR/F (End of Rise/Fall) gate outputs can be used to chain and sequence events
      • Env Level and Offset knobs scale and shift Env Out without changing VCA volume
      • Audio In and Out jacks for passing audio or CV through the VCA
      • VCA CV inputs to use VCAs independently from the envelopes:
        • VCA gain internally connected to envelope output when VCA CV jack is left unpatched
      • Follow input jacks allow for slew limiting, sustain (ASR), and exotic filtering effects
      • Re-trig jumpers allow for re-triggering during rise phase

      The Dual EnvVCA is essentially a Shaped Dual EnvVCA without the waveshaping abilities, ASR trigger mode, or extra 5V envelope outputs.
