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.

Build harmony with Poly Stacking
Capture instant MIDI loops
Rock that Step Sequencer
  • 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.

Sounds great, what do I get inside?

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

While Rhythmizer operates flawlessly in Bitwig for most functionalities, the DAW's architecture currently does not support Bend Mode.

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

Cre8tive Tool

It's such a fun to create new Melodies or Beats from scratch. I use it in Abeton Live 11. The Ultra Mapper is easy to use. Good job👌

Cant find trial

Ver interested to demo but cant find a trial?

Hey LV, the free trial is available on the product page - likely the same page you're reading this reply :-)

Really great

Amazing, particularly for the price, love it!

Thanks for the review, Sam, glad to hear it!


Funktioniert nicht unter Cubase Elements 13

Sorry, aber unter Cubase Elements 13 scheint dieses VST nicht zu laufen. Aktuell vermute ich 48 Euro für "Nichts" ausgegeben zu haben... schade...
