John created an excellent and very clear explanation on this subject, worth copying to a memo file for those not familiar with the workings of BIAB.

One more thing, every once in a while, when I find that the Save with Patches and Harmony doesn't seem to work and the Patches revert to what they were rather than what I've picked, try doing the whole routine *while the song is still playing back* and before it stops. For some reason, sometimes doing that will force the Patch Changes to be at the start of the song and will then work.
