I never had this problem maybe because I only had the 5 original instruments when adding, deleting, copy and pasting, etc, measures in my unfolded songs. The OP stated "I've built a track and entered chords , added soloists, keyboard and other instruments and now I find I want to insert 4 bars into the middle which essentially are intended to copy the previous 4 bars." Note I am assuming the OP used the utility tracks go add those other instruments.

My question to those more familiar with BiaB would adding soloist and utility tracks be the problem?


I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!
