Thanks Bob... Still want to check more into the Saffire 6.

Been using the M-Audio Fast Track Pro and it was fine, but got the Tascam US-144 at the 'hint' of someone in PG Support. The Tascam ASIO drivers seem much more stable and also, I can have BIAB, Real Band, Windows Media player all open at the same time and switch back and forth at any time ! No switching Sound configs to use ASIO (only 1 app), then changing default device to use Media player etc.
