Song MIDI messages

This feature can be added as a custom page button.

Each OpenSongApp song can have stored MIDI messages.  When the song is loaded, the MIDI messages can be sent in order to connected MIDI devices automatically, or manually using the MIDI popup shown.  These messages can be used to change settings on other devices such as BeatBuddy pedals, keyboard patches, etc.

Currently connected MIDI devices are shown (if available).  Clicking on the device name (or nothing selected warning) will take you to the MIDI settings page where you can connect a MIDI device.

A list of currently stored MIDI messages for this song will be shown and each one can be sent by clicking on the item in the list.  MIDI messages can be reordered here and swiped to remove them, however, the best way to edit the song MIDI messages is to click on the Edit button and this will open the MIDI shorthand popup that helps you build MIDI code.
