What is OODA — Portable MIDI Sequencer?
OODA is a MIDI step sequencer app that offers interactive and semi-generative enhancements. It allows users to connect arbitrary steps together using conditional “wormholes” to add structured or random variation to their sequences. OODA’s underlying model is decoupled from its voices, which enables users to interact with their sequences and create melodic variations in real-time without affecting their groove. The app's open-ended sequence grid can be easily configured for almost any use case, from simple melodies and bass parts to semi-generative chords and arpeggios.
1. What makes OODA unique is that you can connect arbitrary steps together using conditional “wormholes” to add structured (or random) variation to your sequences.
2. Instead, you use it to send MIDI (note messages) to other apps, plugins, or hardware instruments that do the actual sound generation.
3. OODA is a fresh take on the classic MIDI step sequencer with interactive and semi-generative enhancements.
4. The standalone app features a simple, toggleable "Sidekick Synth" so you can quickly experiment with OODA.
5. Meanwhile, the OODA AUv3 plugin does NOT generate sound.
6. OODA can be used as a standalone app or as an AUv3 plugin.
7. This allows you to interact with your sequences and create melodic variations in real time without affecting your groove.
8. Another unique feature is that OODA’s underlying model is decoupled from its voices.
9. Of course, you can also send MIDI from the standalone app.
10. AUv3 plugins must be used inside a compatible host.
11. OODA’s open-ended sequence grid can be easily configured for almost any use case.
