The EnvVCA is a compact analog envelope generator with a built-in low-noise exponential VCA. It's a perfect companion to any VCO, whether you trigger it or self-cycle, and/or use the envelope output to modulate something else. With a wide time range from 30 minutes to 10kHz, it can be used as an LFO, slew limiter, audio or CV VCA, ASR/ADSR envelope generator, audio-rate oscillator, and more.
100% analog
EnvVCA features:
Versatile linear envelope generator/LFO
Low-noise, low-distortion, DC-coupled exponential VCA
100% analog
Sliders, switches and Time CV jack controls Rise and Fall times from 100µs (10kHz) to over 30 minutes
With sliders and switches only: ~1.25ms to over 2 minutes
Independent attenuverters for Rise and Fall time
Blue/red LEDs indicate strength and polarity
Cycle button for looping envelopes (LFO)
Trigger input jack fires a one-shot envelope
Cycle gate input jack toggles cycling
EOR (End of Rise) gate output can be used to chain and sequence events
Env Level slider controls output level of the Env jack without changing the VCA volume
Audio In and Out jacks for passing audio or CV through the VCA
VCA gain internally connected to envelope output
Follow input jack allows for slew limiting, sustain (ASR), and exotic filtering effects
Re-trig jumper allows for re-triggering during rise phase
The EnvVCA is essentially half of a Dual EnvVCA, without the VCA CV jack and Offset knob.
