Thanks again Charlie!

This sounds quite complicated so far. Maybe it will make more sense to me once I try it myself.

As another example, let's say I use the multiriff feature on bars 5-8 of the piano and also on 5-8 of the guitar. To bring this back into BIAB on the audio channel does it combine those into a single track? If so I have lost the ability to later handle them separately in the DAW.

Also, what happens to the bars I am replacing in my song? Do they get erased? If not, how can I ever hear the new multiriffs in context inside BIAB?
