But if you have a MIDI player app that can run in the background and can be controlled with MIDI messages, you can combine that app's MIDI playback functionality with the rest of Set List Maker's functionality.
Since Set List Maker uses standard iOS audio frameworks, it can only play audio formats that iTunes can play. Many people have asked about playing Standard MIDI Files from Set List Maker on iOS. Details are in 'To play music from a Standard MIDI File' on the Sending MIDI page: This should eliminate the need for another app like Sweet MIDI Player. UPDATE JUNE 10, 2018: In the new app versions released today, you can attach an SMF file (.mid) to a song and play it back just as you would with a 'real' audio recording.
