DivKid Mutes
Four-channel vactrol mute controller for live performance
4 HP Eurorack module
Mutes is a four-channel audio/CV mute controller for Eurorack, using vactrols (NSL32 optocouplers) for smooth, click-free switching. Each channel has a momentary switch with LED indicator, allowing live muting and unmuting of audio or CV signals with organic, vactrol-softened transitions. It is well-suited for live performance, adding rhythmic gating or sudden silences to a patch.
Features
- Four independent mute channels
- Vactrol-based (NSL32) switching for smooth, click-free transitions
- Momentary switches with orientation (momentary action facing left)
- LED indicator per channel showing mute state
- CV control input per channel
- Mini-jack audio/CV inputs and outputs
- Two-PCB design: Main PCB (circuit) and Control PCB (panel components)
- Semi-DIY kit with SMD components pre-assembled
- Boards connected via 2x4 pin headers and socket connectors
- 12mm spacers secure the two PCBs together
- Power via 2x5 (10-pin) Eurorack power connector
