DOODOV
RACK EXTENSIONS · ONLINE

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.

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.

LooLoo Mini front panel

Single-track stereo looper — record a loop, then perform it.

LooLoo Mini is a 2U stereo looper built to be played, not just set. Record a tempo-synced loop, then reshape it as it runs: a movable window onto the recording, a dedicated stutter section, a spring-loaded speed-bend wheel, plus pitch shift, decay and an external FX send/return. Overdub layering and three loop modes cover the classic looping workflow; full CV in and out ties the loop into the rest of your rack.

The first device in the LooLoo family — Doodov's loopers, all built on the same live-record-into-buffer engine.

SW4-C Multi-Switch Controller front panel

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 Gated Random Generator front panel
GRG-8U Gated Random Generator back panel

Eight channels of gated random CV — one rack unit.

Eight independent CV channels, each holding its own random value until the next gate arrives. Connect any gate source — a step sequencer, a clock divider, a drum track — and each rising edge generates a new random value on that channel, scaled by the Rnd knob and shifted by the Offset knob.

Two passive 1-to-4 CV splitters on the back panel let you route any signal to four destinations without extra devices. No transport lock, no sequencer to configure — gates in, random CV out.

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.
