4ms - EnvVCA
$159.00
Description
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.
