All new in Ultra

  • Custom Scales

    Choose from an extensive list of built-in scales or build your own in any key. The Chroma scale works perfectly with samplers - the device will choose sampler cells at random.

  • Poly Stacking

    Turn single notes into chord-based polyphonic journeys, adding layers of harmonic complexity to transform melodies into electric, scale-focused soundscapes

  • Step Sequencer

    Want to keep things to your groove? You'll love the ergonomic new step sequencer, including our Random Step slider!

  • CC Mapping

    Map randomized CC to virtually any synthesizer parameter with four dedicated map slots, offering precise, real-time modulation for unparalleled control of your synth's architecture.

  • NEW - Drag to MIDI

    Ultra Update 1.1 | Drag everything you just heard from the triangles in Rhythmizer's logo straight into your DAW.

  • NEW - Pitch Hang

    Ultra Update 1.1 | Generate 'repeater' delay style glitches on chosen Groove notes.

  • Record and edit

    Rhythmizer Ultra is merely a starting point. It fires infinite random ideas and inspiration for your curation.

    Record the device's output to MIDI and keep editing in your DAW.

  • Ready to rock

    Mac and PC users, everyone's looked after - Rhythmizer comes in VST3 and AU.

    The device is compatible with almost all major DAWs (check compatibility below) and can send MIDI to anything that receives it: your synths, samplers...even hardware!

  • CPU Optimised

    Open up as many instances as you like - you'll barely see an effect on your CPU. In testing, opening ten instances at once barely hit 1% draw.

Great grooves that put the "organic" back into sequencing!

Really loving Rhythmizer Ultra as the perfect counterpoint to my more traditional "lock step" sequencers. Super helpful, creative and useful musical idea and composition tool! Thanks!

Brilliant bit of kit!

Psytrance to ambient pads or a standard arps, this is an incredible tool to enhance your creativity.
It's just what you need to add flavour to your tracks!
It has a learning curve but when you get there & are taking advantage of what this has to offer this tool will offer a really nice work flow!

Thanks for that awesome review FallenLeaf, it's great to hear you're getting the most out of Rhythmizer!

Check DAW Compatibility


Windows 10 / Mac OS 10.11 or higher (inc M1)


Rhythmizer is compatible with a wide range of DAWs that support MIDI routing between channels and the VST3 format.

We've optimized it for integration with major DAWs like Live 11, Cubase, Logic, FL Studio, Bitwig, Reaper, and Studio One.

Additionally, we have many satisfied customers using Rhythmizer successfully in other DAWs as well.

Known Limitations

  • FL Studio

FL Studio does not support Bend Mode at this time

  • Live

We recommend Live 11, as Bend Mode and CC Mapping are not supported in Live 10, and Live 9 does not support VST3 at all.

  • Reason

Reason is not compatible with Rhythmizer due to its lack of essential MIDI re-routing capabilities.

  • Bitwig

Ensure CLAP version is installed and Note FX version used (since Ultra update 1.1)

• Rhythmizer is not available for Pro Tools at this time.
