FAQ

For lyrics and auto-scroll features, yes — you need something sending MIDI program changes and clock. This can be a USB MIDI controller, a MIDI interface, or a DAW routed through the Mac’s IAC Driver. For just viewing lyrics without auto-scroll, no MIDI is needed at all.

Any controller that sends Program Change messages and MIDI Clock. Common choices: Behringer FCB1010, Roland FC-300, MIDI Solutions footswitches, or virtually any MIDI keyboard. Your DAW (Ableton, Logic, GarageBand) can also act as the clock source.

No hard limit. A band of 5 each viewing lyrics on their own device works perfectly. The server broadcasts updates via WebSocket — bandwidth per device is very low.

Yes — you need an Art-Net to DMX converter node. We test with the Pknight node (~$40–60). Connect it to your network, run a standard DMX cable to your fixtures. DMX lighting is part of the paid upgrade in the upcoming release.

The host app currently runs on macOS only. However any device with a browser — Windows, Android, iPhone, iPad, Linux — can view lyrics by connecting to the Mac server over the local network. Windows/Linux support for the host app is on the roadmap.

Songs are stored as ChordPro .txt files. ChordPro is an open standard supported by dozens of apps (OnSong, Chord!, ChordPro for iOS). If you already have songs elsewhere you can likely export them as ChordPro and import directly.

Yes. All data is stored in standard JSON files. The Show Bundle export/import also gives you a portable backup. Your setup carries forward.

Email midiprompter@gmail.com with details. Include your macOS version, what you were doing, and what happened. Screenshots or recordings are very helpful. We read every message.

The upcoming release will keep a genuinely free Practice tier — ChordPro lyrics and the built-in click track — with the MIDI sync and DMX lighting features available as a paid upgrade. Final pricing is being set now. Beta participants will get early-access pricing at launch — sign up to be notified.
