Work with unlimited tracks

  • PolyBud is a multitrack polyrhythmic sequencer.

    You can add as many note or MIDI CC tracks as you want.

    Each note track has the note, velocity, gate and ratchet modes.

    The MIDI CC tracks are great for modulating synth parameters.

    Also, you can assign different MIDI Channels to the tracks for controlling different synths.

    You can create unlimited patterns and you can create unlimited steps per pattern.

Create polyrhythmic sequences

  • You can assign different number of step lengths to the each mode.

    Setting different step lengths would introduce immediate polyrhythmic results.

    Even with less amount of step lengths you can create long, polyrhythmic sequences.

    Each note and CC track can run in different rates for polyrhythmic variations.

Always get musical results

  • PolyBud's music theory engine offers more than 110 scales.

    You can also use your custom scales that you created in ScaleBud 2!

    Each note track share the same key/scale pair so they always produce musical results.

    Keys and scales could be changed in realtime while the sequencer running.

Take advantage of the AUv3 Plugin

  • PolyBud runs as standalone app as well as AUv3 MIDI Plugin.

    You can create AU presets and use AU parameters of the AUv3 plugin.

    PolyBud offers multiple AU parameters where you can control or even automate every single parameter.

    The standalone version of PolyBud supports Ableton Link.
