Auto Bass is a powerful MIDI generator application developed by Cem Olcay for iPhone. With Auto Bass, users can effortlessly create dynamic basslines and melodies through an editable algorithm. The app offers a range of customizable parameters to tailor the generated sequences to your liking. Adjust complexity to break longer notes, set density for note/rest ratio, spread for note range, offset for note shifts, swing for note sequence start position, and slide for sliding note percentage.

Additionally, global adjustments such as gate length and note velocity can be made using the gate and velocity parameters, with added randomness introduced through gate variety and velocity variety knobs. The app's editing menu provides essential tools like accent mode for adding accented velocity, slide mode for incorporating slides, move mode for pitch adjustments, transpose for key changes, and nudge for sequence alignment.
