I finally got a midi file to load and play using the Aria Player, however, the playback sounds nothing like the what it should sound like. It's a slow and almost resonantly ominous buzzing. I am using a midi file that I exported from Musescore of just a piano part. The instrument I picked from the Aria Player was the studio piano. 

I'm using windows and I have GPO 5

Please Help,

Fredly H
