If by "downloaded karaoke files" you mean pirated stuff off the internet, you probably won't get much support here as MTU as well as most of the members here are opposed to using music you did not purchase.
MTU products were created and sold with the intention of protecting, preserving and enhancing karaoke music that was legally obtained, not to further the demise of the karaoke industry.

And if that's not what you meant then I apologize and please disregard this post.
