Tap to Sibelius

1. Drag "Tap to Sibelius" onto the Applications folder here, then open it.
   Look for the small note icon in the menu bar, top right.
2. Allow keyboard access when macOS asks, then turn on Launch at login.
3. Optional: put TapToSibeliusPanel.plg in
   ~/Library/Application Support/Avid/Sibelius/Plugins/Other/
   and restart Sibelius. It adds Plug-ins > Tap to Sibelius with the steps.
4. In Sibelius: File > Preferences > Input Devices.
   Tap to Sibelius: Use = Yes, Type = MIDI Keyboard.
5. Select a bar, start Flexi-time yourself, wait for the count-in, tap K.
