AUv3 Generative MIDI Sequencer

  • MelodyBud is a generitave MIDI sequencer with great randomisation features.

    You can set each step's note, velocity, gate length, ratchet and glide values.

    Each mode can be randomised per pattern.

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

Parameter Locking per Step

  • You can enter the parameter-locking mode by tapping a step's number on the top of the sequencer.

  • When you're in the parameter-lock mode, you can set randomisation values for that step.

  • If a step has a parameter lock for any mode, the sequencer will apply those values instead of the global values.

  • You can create very rich sequences by assigning individual randomisation values per step.
