Thanks for looking into this Mac.

I use the Roland VSC DXi, driver latency says 104 but I've never worried much about latency as I play guitar and don't use Midi Thru.

But - latency got me thinking. So, the problem fixed after noting that (doh!) I'd installed the 9.5 BB.exe onto the external hard drive. Moving this back to the C drive fixes this problem.

An interesting thing I noticed this morning is the Conductor mode (Enabled Control by Qwerty) works great on all middle choruses (I have it set to execute changes at the Next Chorus). However, when the song is in the final chorus and I command it to go back to middle chorus, the audio does this flawlessly at the end of the chorus - but the black moving bar display jumps immediately to the beginning of the chorus and stays out of synch with the audio.

All considered, still very happy that the audio glitches are fixed for this realtime-redirect function, Surely all who use BIAB live in impov settings will be very happy with this. I know of no other product that supports live use.
