Is it a VST? If so you likely can have Reaper scan for it (unless you know where it is) and select it as the effect you want. Look for it in the BIAB/RB files on your hard drive. Perhaps someone either here or at PG an tell you directory they are in. I don't know where they are.

I assume by "harmony efx" you mean the vocal backing tracks?


I am using the new 1040XTRAEZ form this year. It has just 2 lines.
