• 2Envelope Circuit
• 3VCA Functions
• 4Eurorack Ready

Dynamically control and shape your Eurorack audio signals with the 4ms Dual EnvVCA, a dual analog envelope generator slew limiter, and VCA. Each of the two channels is identical, and they can be used separately or together. The waveform of each envelope can be controlled with a slider or CV without changing the envelope timing.

The module’s wide time range and plethora of CV inputs and attenuverters allow it to be used as an LFO, audio-rate oscillator, slew limiter, ASR/ADSR/complex EG, independent audio/CV VCA, envelope follower, side-chain processor, and general utility module. The Dual EnvVCA ships with a ribbon power cable and mounting screws.

Envelope Circuit

• 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 ~1.25 ms (800 Hz) to > 2 minutes
  • Time CV jack extends time range: ~125 s (8 kHz) to ~10 minutes
  • Independent attenuverters for Rise and Fall times
  • 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

VCA Functions

• Audio In and Out jacks for passing audio or CV through the VCA
• VCA CV inputs so you can 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 retriggering during rise phase
