Hello goofeyfoot,

If you would like to send in one of your songs you are specifically having issues with for testing, we can take a look at it and see if there might be something causing it. To do so, you can attach it to an e-mail at support@pgmusic.com.

Also, when it comes to some tracks playing and some not, did you happen to be working with a mix of MIDI versus Audio? I am wondering if perhaps something just needs to be adjusted in your MIDI or Audio settings.

Cheers,
Ember
