To play an XMIDI file, follow these steps:

1) Allocate an HSEQUENCE with AIL_allocate_sequence_handle.

2) Load the file from the disk with AIL_file_read (or your own file IO routines).

3) Call AIL_init_sequence to point the HSEQUENCE at the loaded disk file image.

4) Play the file with AIL_start_sequence.

To play a standard MIDI file, call the AIL_MIDI_to_XMI function to convert the MIDI file into an XMIDI file image and then follow the XMIDI steps.
