System at place makes sound mono? Destroys result?

[jahern]

I made a vocal reduced file(vr2...). After I made the vocal reduced file, then with another program I patched back in (paste over) some of the sections where the vocalist doesn't sing. I made a cdg using khp and microstudio. It sounded as I expected and I was excited about doing the song. At the place where I sing, the patched in sections played well. the vocal reduced sections were horrible. The voice was soft, but clear and discernible, and everything else was extremely muffled.

I scratched my head and went home. I have found that I am getting a similar result when I attempt to convert the wave file to mono. I think that my place is using mono so that all its speakers have equal sound.

What is my next step? I have tried recording the file again through a line-in situation. Conversion to mono still has this horrible result. I have experimented and had similar results with other vocal reduced files that have no sections patched back in.

If there is a solution Heeeelllp!!
