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.

Completely. Once the fixture library is downloaded (done once at home, ~25MB), MidiPrompter runs 100% offline. No cloud services, no login, no subscriptions.

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.

All your songs, setlists, and lighting setups are stored in standard JSON files on your Mac. The Show Bundle export/import gives you a portable backup you can move between machines or keep as a safeguard. Your data is yours and stays local.

Yes — the Practice tier is free forever, with no account required. It includes ChordPro lyrics, auto-scroll, and the built-in click track. MIDI sync (program-change song loading and MIDI-clock auto-scroll) and DMX lighting are the paid features, unlocked with a one-time $49 license that also includes a year of updates. The version you buy keeps working forever. MidiPrompter launches soon — sign up to be notified.

No. It's a one-time purchase, not a recurring subscription — you're never auto-charged. Your license is perpetual: the app stays unlocked forever, and you get every update released in the year after purchase. After that year, your version keeps working indefinitely; you can renew any time to get newer releases.

After purchase, your license key is emailed to you. In MidiPrompter, click 🔑 License, paste the key, and MIDI sync and DMX lighting unlock immediately. Activation is verified on your Mac, so it keeps working offline at gigs — no internet needed once activated.

Your license activates on your Mac. You can remove it from one machine (in the License panel) and activate it on another — handy if you switch to a backup laptop for a show.
