The Xtra Styles are completely editable. Every Style, MIDI, Supermidi or RealTrack, is completely editable.

Another option you may want to experiment with is to create Medley tracks. Each Legacy Channel (1-7) in the Mixer can have up to 10 different instruments on it. A quick way to audition this feature is to Select Medley Styles from the Stylepicker. These are Medleys created by PG Music staff that are programmed to work seamlessly into the chord chart of your song. These medleys showcase some of the various ways to trigger the instrument changes. They can be programmed to change every two bars, four bars or 8 bars, by part marker and you can manually create your own multiple instrument track to change instruments at any bar. Note that it can be any count of instrument changes from one to 10 and importantly, instruments do not have to be different instruments. Programmed changes can be two instruments switching back and forth multiple times on a track. Do this on two separate channels but using the same two instruments allows for some very complex arrangements to be created within BIAB without ever leaving the program for further processing in a DAW or RealBand.

Bouncing mixes of multi instrument channels to audio and importing them back into your project and placing them onto legacy channels as Performance Tracks develops a BIAB song project of dozens of instruments onto dozens of tracks. Using each of the 7 channels to interchange 10 instruments totals to 70 instrument changes.

An interesting thing I've noticed but am only speculating to how the results come about is the fact that the BIAB generation engine 'reads' ahead and 'sees' the upcoming instrument change and in turn 'selects' more appropriate instrument one ending bar audio and instrument 2 intro bar audio and cross fades wonderfully. You will encounter instrument changes where the audio of the two instruments simultaneously overlap. That requires some manual work to accomplish in any DAW but is done automatically within a BIAB project using the multi instrument feature.

This feature in BIAB 2020 has added features and enhancements from previous years and it's well worth the time to explore.
