Requirements and FAQ
What you need to run Oxidzr, what it connects to, and short answers to the questions people ask first.
Requirements
| Device | An iPad running iPadOS 16 or later. |
| Sound | Oxidzr makes no sound of its own. You need a synth app, a drum app, or hardware with a MIDI input. |
| As a plugin | A host that loads AUv3 MIDI processor plugins, such as AUM. |
| Hardware | USB MIDI devices and interfaces, and Bluetooth MIDI devices once they’re connected. |
| Help (?) | Written answers need iPadOS 26 on an iPad that supports Apple Intelligence, with Apple Intelligence switched on. Without it, Help shows the matching sections of the guide instead. Everything else works without it. |
Questions
What is Oxidzr?
Oxidzr Sequencer is a MIDI step sequencer for iPad. It runs eight sequencers at once, each in one of nine modes: Mono, Poly, Chord, Multitrack, Stochastic, Matriceal, Domino, Saga and MIDI Player. It comes as a standalone app and as an AUv3 MIDI plugin.
Does it make sound?
No. Oxidzr plays other instruments by sending them MIDI notes and controllers. The only sounds it makes itself are the standalone app’s metronome click and drum loops.
What’s the difference between the app and the plugin?
The standalone app has its own play button, tempo, MIDI Out, MIDI clock, metronome, Ableton Link and Help. The AUv3 plugin follows the host’s transport and tempo, sends its MIDI to the host to route, and is saved with the host’s session. Both have the same sequencers, modes, patterns, mod lanes, Arp and step recording.
Can it control hardware synths?
Yes. The standalone app sends to one MIDI destination of your choice, such as a USB or Bluetooth MIDI device, on up to 16 channels. See Sequence hardware synths, and Eurorack for modular.
Does it send and receive MIDI clock?
It sends MIDI clock, Start and Stop from the standalone app. It doesn’t follow incoming MIDI clock. To share a tempo with other apps and devices, use Ableton Link. As a plugin it follows the host’s tempo.
Does it support Ableton Link?
Yes, in the standalone app: shared tempo, bar alignment and optional Start/Stop Sync. In the plugin, use the host’s Link support.
Does it receive MIDI?
Yes. It listens to every MIDI source on the iPad, plus its own virtual input. Incoming notes drive the Arp, Rec (step recording) and Thru.
Can I use MIDI files?
Yes. MIDI Player mode loops a standard MIDI file (type 0 or 1) on one sequencer, in time with everything else. You can loop part of it and transpose it.
Does it need an internet connection?
No. Everything, including Help’s on-device answers, works offline.
Does it collect any data?
Nothing that identifies you, and never your music. To fix problems and see what gets used, the app sends crash reports and anonymous usage statistics, such as which screens open and which controls are pressed. It has no accounts, ads or tracking. See the Privacy Policy.
Is it released?
Yes. Oxidzr Sequencer is on the App Store for iPad.
Where is the full manual?
The How to guide covers every mode, control and screen. In the app, ? answers questions about it in your own words.
