Control the Algorithm

  • Auto Bass has a badass algorithm for generating awesome basslines and melodies.

    You can tweak every bit of the algorithm in your taste for generating a bassline that fit your needs.

    • - Complexity breaks the longer notes into shorter notes.
    • - Density sets the note/rest ratio.
    • - Spread sets the range of the notes in the piano roll.
    • - Offset shifts the notes on the piano roll.

Chord intervals for richer sounds.

Choose your style

  • You can change the gate length and velocity of the notes globally with the gate and velocity parameters.

    Gate variety and velocity variety knobs introduce randomisation to the notes.

    You can set the bassline pattern's duration with between 1-bar long to 64-bars long.

    Swing shifts the start position of the every other note in the sequence.

    Walk type rearranges the notes on the piano roll without regenerating the whole sequence.

Sequence the Transpose

  • You can tranpose the sequence with an external MIDI keyboard or a MIDI sequencer.

    The edit menu on the top left exposes the editing options.

    • - Accent mode let's you mark any note on the piano roll to be an accented note.
    • - Transpose control lets you change the sequence's key.
    • - Nudge control shifts the whole sequence to the left or right.

  • Auto Bass runs as standalone app as well as AUv3 MIDI Plugin.

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

    You can modulate the parameters with ShiftBud.

    You can change the patterns with PatternBud.

    You can also control the key and scale with BrainBud.
