I am using RB 2009.5
I have used the command "merge audio and DXi tracks to stereo wav file."
This seems to add an additional "track" that behaves like a hung midi sound.
it appears on the converted wav file but then can also be heard when playing the file in the RB window. If I hit the panic button, the extra sound disappears. However, I can't seem to get a wav file made without the extra.
