Removed dependency on the MIDI library.Cleaned up examples and added additional comments.Allow user code to control ticks directly for sync with external MIDI clock.Changed timebase to be 'tick' based & corrected algorithm.Documentation extensively revised and now in dOxygen format.Renamed MD_MIDIFile Library for consistency with other MajicDesigns libraries.Bug fix - SdFat changed behavior, needed change TIME SIGNATURE handling case.Changed SHOW_UNUSED_META to 0 as it should have been all along.Added handling of meta events through callback (R.Fixed tick calculation by eliminating the time signature in calc (R Foschini).Changed handling of SYSEX and META events with data bigger than buffer (R Foschini).Fixed buffer overflow in SetFilename().Changed CLI example to use MD_cmdProcessor.Changed error codes to defined constants.

Deprecated setFilename(), use load() with file name specified.

Removed internal buffer for file name.

Added isPaused() and isLooping() methods.

The interface can be stand alone or built onto an Arduino shield, as required.

MIDI interface hardware described in this documentation.

Used by the library to manage the SD card file system. The MD_MIDIFile library uses the following additional libraries and may need additional hardware components If you like and use this library please consider making a small donation using PayPal External Dependencies Time ticks are normally generated by the library during playback, but this can be taken over by the user program if different time or synchronization with external MIDI clock is required. SMF may be automatically looped to play continuously. SMF playing may be controlled through the library using methods to start, pause and restart playback. This allows the calling application to manage sending to a MIDI synthesizer through serial interface or other output device, such as a MIDI shield. SMF can be opened and processed, with MIDI and SYSEX events passed to the calling program through callback functions. This library allows Standard MIDI Files (SMF) to be read from an SD card and played through a MIDI interface.
