What you're hearing is the aliasing sound of a low sample rate, 8-
bit sample. It is a part of the sound. I have an SK-8 and that
buzzing sound is most noticeable on the "guitar" preset. You will
hear it on any of the brighter tone presets. It's simply a part of
the el-cheapo keyboard process. Viva el-cheapo, I say!!

Cheers, Graham
