Generative tools for Reason. Built for the curious.

Doodov makes Rack Extensions that turn Reason into a generative instrument: CV routers, gated random generators, sequence and phrase engines. Hand-crafted, focused devices that do one thing well — and let you steer the variation.

// About

What Doodov is

Doodov is a one-developer studio designing modular tools for Reason. Each device is conceived around a single musical idea — channel switching, weighted randomness, transport-locked phrase generation — and shipped as a focused 1U or larger Rack Extension. The work began with the SW4-C Multi-Switch Controller and continues with the GRG and SPG families and beyond.

The brand is small, the devices are deep, and the documentation is honest about how each one fits into a generative rack.

SW4-C

Shipping

Multi-Switch Controller — 4-way CV router for real-time and generative work.

The SW4-C is a 4-way switch aimed at real-time performance and "Kontrolled generative" music. Three CV inputs route to one of four output sets, sequentially or by weighted-random choice. Front panel and CV-mod control over per-channel weights, repeats, and gate behaviour. Designed to sit at the heart of complex generative setups in Reason.

Also useful as an 8-knob, 8-button mini-controller for any Combinator-driven patch.

GRG-8U

In Deployment

Gated Random Generator, 8-channel — held-random CV with per-output range, plus passive splitters.

Eight independent random generators on a single 1U panel. Each channel: random amount, offset, and a CV output that holds its value until the next gate. Two passive 1-to-4 CV splitters on the back panel for quick fan-out in any patch.

Designed to feed SW4-C's chance probability inputs, but useful anywhere you want a held random voltage that responds to a gate trigger.

// What's next

In development

Doodov continues to build modular tools for generative work in Reason — CV utilities, gate sequencers, audio devices. Each one is designed around a single musical idea, and each one ships when it's ready, not before. Announcements happen at beta or release, never earlier.
