I am certain this is not a bug but I can't figure out what I am doing wrong. I have a tune wih some proprietary licks in the intro that I want to copy to the tag. I cannot copy using to from to tag. Since that did not work I tried recording into the tag and that doesn't work either. I think I have tried every possible setting. Any ideas?

What version of BIAB are you using?

I am able to do this. If the Number of Choruses is the default value of 3, you would want to Copy To chorus 3, since that would be the final chorus and the tag is considered part of that final chorus. Then just specify the measure number. Make sure you Uncheck Copy 1st Chorus to Whole Song.

If that does not work, please give us details of the exact steps you are using.
