Frequently asked questions
Is Ocarino on the App Store in mainland China?
Not yet. Ocarino is not available on the App Store in mainland China; it is available in every other country and region.
Does the Mac version support VST plug-ins?
No. On Mac, Ocarino loads Audio Unit plug-ins (AUv2 and AUv3). VST and VST3 are not supported. Most plug-in makers also ship an AU version; install that one.
How do I restore my Ocarino+ purchase?
In the app's Settings, open the Ocarino+ page and tap Restore purchase. Make sure the device is signed in with the Apple Account you used to buy it.
My MIDI device does not show up
- USB devices: check that the device is powered on and that the cable and adapter are firmly connected. Devices that need external power may need a powered adapter or hub.
- Bluetooth MIDI devices: pair them inside Ocarino, not in the system Bluetooth settings. On the Routing page, tap Pair Bluetooth device, and check that Ocarino has Bluetooth permission in the system Settings.
- Network MIDI: check that the device and the network MIDI host are on the same network, and that Ocarino has local network permission.
- The device appears but nothing happens: check in the MIDI monitor whether messages arrive, then check in Settings under MIDI which MIDI channel the device listens on and which tracks it plays.
There is no sound
- Check that the device volume is turned up.
- Check the current output device in Control Center, for example whether Bluetooth headphones are still connected.
- In the app's Settings, open Audio to see which output port and format are in use. To play sound together with other apps, turn on Play alongside other apps.
- In the Mixer, check that the channel is not muted and its fader is up. On the Routing page, check that the track is connected to a channel.
- When playing the on-screen keys on the Harmony page, check that Make sound is on.
Where is my data stored?
Everything stays on the device and is never uploaded. "Documents" below means the Ocarino folder under On My iPhone or On My iPad in the Files app, and ~/Library/Containers/com.wheatfox.ocarino/Data/Documents on Mac.
- Projects
- Documents/Ocarino
- Imported sample packs
- Documents/Ocarino/Packs
- Imported wavetables
- Documents/Ocarino/Wavetables
- Saved sounds
- Documents/SavedSounds.json
- Imported voice banks
- Documents/ImportedVoices.json
- Imported single samples and recordings
- The app's own storage (~/Library/Containers/com.wheatfox.ocarino/Data/Library/Application Support/Samples on Mac), not visible in the Files app
- Practice records and your Ocarino+ name
- The app's own storage, not visible in the Files app
The current project is saved automatically when you switch to another app, open another project or quit Ocarino, and you can save at any time. To move data between devices or back it up, copy the files in Documents to iCloud Drive or elsewhere. Deleting the app deletes all of the above; samples and recordings in the app's own storage cannot be backed up through the Files app, so export the ones you need first.
Which devices are supported?
iPhone and iPad with iOS 26 or iPadOS 26 or later; Mac with macOS 15 or later; Apple Watch with watchOS 26 or later, paired with iPhone. Beat, bar, tempo and key analysis of samples requires iOS 27, iPadOS 27 or macOS 27.
