Thank you for the info, Jim. I'm not using slot 1 as it is typically occupied by a MIDI instrument (I'm using MIDI instruments only as it--I think--makes it easier to export the BIAB project to MIDI for use by other DAWs).

That said, I have been using slot 1 in the Master track because it's available and appears to be working properly. Currently slot 1 in the Master track hosts PG Reverb and slot 2 hosts Waves Abbey Road Studio, and both appear to be working fine.
