The Dual EnvVCA is a workhorse for anyone serious about modulation. Its dual-channel design and fader-based controls give you a ton of expressive control over your sound. It’s a great choice for experimental sound design or creating evolving textures in ambient or drone patches.
Product Description
- 4ms Dual EnvVCA
- Eurorack Module
- Two-channel function generator with VCA
- Per channel: AD envelope with fader for rise and fall times (each with three selectable time ranges)
- Level and offset control for envelope output (range: -10 V to +10 V)
- Trigger input
- signal input and cycle button
- CV input for controlling envelope times with adjustable intensity for rise and fall
- VCA audio input and output
- Envelope output is normalised to VCA CV input
- End of Rise and End of Fall trigger outputs
- Envelope signal outputs and OR logic output
- Power consumption: 156 mA (+12 V) / 131 mA (-12 V)
- Width: 16 U
- Depth: 24 mm
PROS
- • Dual channels offer incredible flexibility for complex modulation.
- • Fader-based time control is intuitive and provides tactile precision.
- • OR logic output expands routing possibilities significantly.
- • Robust 4ms build quality ensures longevity and reliable performance.
- • Wide output voltage range (-10V to +10V) provides ample headroom.
- • End-of-rise/fall triggers enable precise sequencing and triggering.
CONS
- • Limited time range selection compared to more modern envelope modules.
- • Normalization, while convenient, can restrict certain patching options.
- • Power draw is a bit higher than some other modules in its class.

Frequently Asked Questions
The faders offer a more immediate and tactile feel, allowing for real-time adjustments that are difficult to achieve with standard potentiometers. It's particularly useful for live performance or dynamic sound design.
Yes, the module functions as a dual VCA, with the envelope output normalized to the VCA CV input. However, its strength lies in the envelope shaping capabilities, not just simple gain reduction.
It's a standard Eurorack normalization – easily broken with a jumper wire or by simply disconnecting a patch cable. This allows for more complex routing and CV control of the VCA section.
