It’s actually very easy to convert MIDI files to the SMAF format. Firstly you need to download a free piece of software from Yamaha called SMAF Sound Decorator.

Once you have downloaded it, install it and load it up. Once loaded you will be presented with a nice looking control panel. Now drag your MIDI file on the application and you will see the little window at the bottom of the screen telling you various bits of information, the last line should say “Successfully completed”.
