4MS EnvVCA - Black

The EnvVCA is 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.

• Width: 8HP
• Depth 24mm
• Power: 83mA @ +12V / 81mA @ -12V

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.
