I've been having an issue with pianissimo sounding a slight, annoying buzz/vibration sound behind a note when it is played. Generally on higher keys. I had this issue in Mixcraft 7 and still in Mixcraft 8. It does not matter where i have the volume set on my monitors (M-Audio AV-40), my recording interface (Avid ElevenRack), or in mixcraft itself. The buzz is always there. I don't believe it is my monitors, because it also happens when I use any headphones.
I do not get this buzzing sound in any other of the Mixcraft VSTs, just Pianissimo.
The sound happens while monitoring, recording, playback, and even after I publish to MP3, it's still there.
Here is a link to soundcloud of a small clip that my brother did of the Interstellar theme using the grand piano preset on pianissimo. https://soundcloud.com/user-619151363/pianissimo-buzzing2
Any help in diagnosing this sound would be greatly appreciated.
