Duration based steps

  • PatternBud steps can have a duration of bars, beats, note values or seconds.

    You can set each pattern's duration very specifically which is a unique feature.

    Each step can have a MIDI CC value which is sent on the beginning of the step.

    Steps can also have multiple, customisable actions.

Polyrhythmic patterns.

Step Actions

  • Each step can have multiple actions which is great for creating randomised, generative sequences.

    An action could be jumping to a specific or a random pattern - which could be used for pattern chaining.

    An action could be jumpting to a specific or a random step of a track.

    Also, you can set MIDI CC actions for additional custom triggers.

    Actions are executed on the end of the step's progress.
