App Description

OODA is a fresh take on the classic MIDI step sequencer with interactive and semi-generative enhancements.

What makes OODA unique is that you can connect arbitrary steps together using conditional “wormholes” to add structured (or random) variation to your sequences. Another unique feature is that OODA’s underlying model is decoupled from its voices. This allows you to interact with your sequences and create melodic variations in real time without affecting your groove.

OODA’s open-ended sequence grid can be easily configured for almost any use case. Anything from simple melodies and bass parts to semi-generative chords and arpeggios, OODA can do it all with a little creativity!


Features:

- Record sequences up to 64 steps with the in-app keyboard or an external MIDI device
- Interact with your sequence on the fly using four “action” buttons
