Generative tools for Reason. Built for the curious.

Stepling is a 2U step sequencer modelled on classic vintage step-sequencer hardware. Each of its eight stages holds a pitch, a pulse count (how many steps the stage lasts), a gate mode, a ratchet pattern, and slide and skip switches — so a single column of controls describes a note, how it repeats, how it's gated and how it slides. Every pitch is quantised to one of thirty scales, and the stages can run in sixteen play directions, with a live keyboard on the display showing what's in key.

It's a CV device — it drives any Reason instrument over pitch and gate rather than making sound itself. Seventy CV inputs reach nearly every parameter, global and per-stage, down to the scale, direction and sequence length; eleven outputs include a direct pitch output for each stage, so you can link units into harmonised or rhythmically independent layers. The compact device in Doodov's step-sequencer line.

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.

Splitfire Furioso is a 2U live sampler designed around one idea: accept hard constraints, design for stacking. Three voices, sixteen slices, roughly four seconds of buffer, tape-only playback. Five instances fit in 10 rack units and use less RAM than a single full-sized sampler.

The device plays back captured audio two ways. Slice mode maps one slice per key from a settable root — each note triggers its own slice of the recording. Pitch mode plays the whole sample pitched across the keyboard, with start and end knobs defining the playable region. Slicing is automatic (transient detection) or manual (equal divisions, 1–16), and either can be overridden in real time via the cv_slices CV input.

Twenty CV inputs make every musical parameter externally drivable: speed, envelope, loop length, stutter rate and window, pitch region, slice count and selection, plus gates for record, clear, mute, and stutter engage. Two CV outputs (current slice count, playhead position) make self-syncing patches straightforward. Per-voice direct outputs route each voice to its own mixer channel for parallel processing.

The voice machinery is click-free across every combination of voice mode, play mode, and loop mode. Recording over actively-playing voices is safe — voices continue through an atomic buffer swap protected by a per-voice fade-in. Unforgiving CV abuse produces musically useful chaos rather than digital noise.

Built on the same live-record-into-buffer engine as the LooLoo family, specialized for compact stacking instead of single-track loop performance.

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.

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.
