I have been using Samplitude Pro X for a number of years and it seems to perfectly fit along side BIAB, it users 'audio objects' to edit in a similar way as block chording with BIAB
There is an official free version called Samplitude Pro X Silver which still has the same audio engine as the big brother and comes with a wealth of very good plugins and the Vandal Guitar SE emulation software.
