Pokey is a passive Eurorack module designed for expressive switching, routing, and mixing of two signals — whether audio or CV. At its core, Pokey is a hands-on performance tool:

• Smooth manual crossfading between two inputs
• Voltage-controlled switching and blending via CV or trigger
• Works equally well with audio and control signals

Because it’s fully passive, it requires no power and integrates easily into any system. What you can do with it:

• Manual performance mixing — Blend two oscillators, textures, or modulation sources by hand.
• CV-controlled switching — Animate transitions using envelopes, LFOs, or triggers.
• Lo-fi “Lopez gate” style drum shaping — Use triggers to rhythmically open audio sources for percussive effects.
• Creative signal routing — Build evolving audio paths or modulation networks in compact systems.

Pokey is simple in concept but powerful in practice — perfect for small performance systems and modular setups where space and immediacy matter.
