Most software drum machines are built around the same basic gesture: a grid of steps, and a finger deciding which ones are on. AudioThing’s Orbita, released this week, starts from a different premise entirely — instead of programming individual hits, you tell each track how many hits it should have, and a Euclidean rhythm algorithm spreads them as evenly as mathematically possible around the cycle.
Math instead of a grid
Euclidean rhythms are a well-known idea in algorithmic music — the same distribution logic behind Euclid’s greatest-common-divisor algorithm turns out to produce a huge number of real-world rhythmic patterns (son clave, bossa nova, various West African bell patterns) when you ask it to space out N hits across M steps as evenly as possible. Orbita puts that generator front and center across eight independent tracks, each with its own step and hit count, so a track can be nudged from a sparse four-on-sixteen pattern to a dense, near-continuous one just by changing two numbers. From there, each track can be rotated via an offset control, pushed off the grid with swing, and reset at custom points to realign patterns that would otherwise drift out of phase with each other — the kind of interlocking, evolving polyrhythm that’s tedious to hand-program but falls out naturally once the generation itself is doing the spacing.
Still a real drum machine underneath
The generative core doesn’t come at the cost of sound-design depth. Each of the eight tracks gets its own filter (low-pass, high-pass, band-pass, or notch) and a dedicated LFO that can modulate pitch, pan, volume, cutoff, or resonance, and the whole thing ships with 36 factory sample banks spanning acoustic kits alongside classic drum-machine sources like the 808, CR-78, and DD-10 — plus a bank editor for loading and organizing custom samples. A performance mode turns the same instrument into a conventional eight-pad drum machine with assignable MIDI notes, for anyone who wants to play live over a running Euclidean pattern rather than only sequence one.
Availability
Orbita is out now for macOS, Windows, and Linux as a 64-bit VST2/VST3/AU/AAX/CLAP plugin, plus an iOS version available both as a standalone app and an AUv3 plugin. It’s launching at $39 (a discount off its $69 regular price), with one license covering up to three machines and no dongle required — a free demo is available for anyone who wants to hear the pattern generator before buying in.
