Controlled Randomness or Chaos

  • You can create different patterns for different key/scale pairs.

    When you change a pattern, BrainBud will broadcast the new state to the connected Bud apps immediately.

    You can also use PatternBud for sequencing those changes.

    If you feel adventurous, you can also tap the Randomise button for a journey to the complete unknown.

Chord intervals for richer sounds.

Take advantage of the AUv3 Plugin

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