How to play MIDI file?

FMOD Engine
1

I tried to load a MIDI file using createSound or createStream but it returns FMOD_ERR_PLUGIN_RESOURCE. I don’t understand what it means. So is there any example code to play MIDI file easily using a single API to load and a single API to play? If you insist a common user take a decade to be an expert before using FMOD to play MIDI file, can you show me a learning path? Thanks.
