Matt, Dan, Pipeline thanks for trying.

I had two projects A and B.
1)I opened project A selected chord grid->copy.
2)Opened project B (the A closed, I assume) and "pasted" chords.

After wrestling with this for a while I tried to export project as stems (individual wavs) and it gave me "Rendering failed" error. Rebooted. I tried it with different audio card / driver, same thing. So I opened another project from last month and tried to render it for testing purposes, also got "render failed" message.

So...I figured that something must got corrupted in software itself. So I've done a BIAB factory reset and EVERYTHING WORKED fine.

What I suspect is happening is something gets corrupted in software when copying/pasting chord sheet between projects. About a year ago similar thing happened. All chords became red in color and it would not play and I had to factory default the program to fix it. Now I remember, that is why I stopped doing this "between" project copying and pasting smile Not long ago a fellow posted in one of the topics that his chords "turned red", interesting if he was doing some copying too.

Pipeline, Thank you for: import chords from MGU tip. Seems to do the job.

Misha.
