I am trying out my new copy of BIAB 2009.5 and this new conflict is arising associated with the use of VSTi instruments (pianos).

Situation:
Load BIAB 2009.5 per usual with MME audio settings. No Dxi. Output through SD2 module per usual (all exactly same as previous 2009 version).
Load EITHER one: "True Pianos Standalone" or "Pianoteq 3 Standalone". ASIO sound card (Indigo) settings.
No MIDI thru.
Call a style in BIAB. No Real Tracks available. ALL Real Drums available.
Result:
(1) Error message re: "cannot load wave file, may be in use etc."
(2) A few seconds later -- style loads and plays (without wave files?).

Error repeats whether BIAB or either of the standalone instruments is loaded first.

Variations:

(1) Loading EITHER of the piano instruments via a host (in this case Brainspawn Forte Ensemble latest version) appears to remove conflict and error message. This was not necessary before 2009.5 -- standalone versions worked perfectly.

(2) Changing MME and ASIO speaker output settings so that BIAB uses one set (1 & 2 for example on the Indigo) and the standalone instrument another (say 3 & 4) also seems to remove the conflict -- but this was never necessary before.

Perhaps someone with these or other VSTi usage can check this out and confirm? It's not the end of the world, but many times I prefer using the VSTi setups in the standalone mode -- less complicated.
