The join list is empty — no rooms found
Automatic discovery is often unavailable on iOS (a system-level issue, not this app). Type the four-digit code instead — that is the main path, not a fallback. The code is at the top of the host’s lobby screen.
I typed the code and it still will not connect
Three things, in order: are both devices on the same Wi-Fi (two bands with the same name still count as one); is the host still sitting in the lobby (leaving closes the room); and did you tap “Don’t Allow” on the local-network prompt — that lives in Settings → OverDrive → Local Network.
The playhead moves but I hear no backing track
Backing tracks are solo-only, by design. Several devices playing sustained audio 20–50 ms apart sounds like echo and flanging. If you want a click in a room, let one device play it out loud.
I plugged in an interface but it recorded the built-in mic
The confirmation sheet before recording shows the current input. iOS only switches once it sees the USB interface: plug in first, then start the recording.
The stem separation door is greyed out
The separation model ships inside the app bundle. If you are running a build you made yourself, the model has to be generated once (see the repository docs). App Store builds include it.
How do I move my library to a new phone?
Each chart exports as an
.odsong file (AirDrop, Files, any messenger). Open it on the new device and it imports. An iCloud backup restore brings the whole sandbox across too.Contact
Feature requests, bugs, anything. Including your device model and iOS version makes it much faster.
