Recommendations:

1. Performance seems much better if the samples are on an SSD drive.
2. If attempting to use in an actual packaged game the paths provided to sfizz should be the correct absolute paths for the target machine
3. Sfizz can take a few seconds to load a large library, when used to render midi it's better to load play the metasound first and to give Sfizz a chance to load before sending play on the midi transport.
