Hi Mac,
Sorry for the delay...

I tried your file and it went as it should in my setup (both with and without External synth)

I tried it with loop on and off - no difference
I tried it with generate ending on and off - no difference

I am using an external synth a KORG 05R/W selected with my Edirol UA-20 interface.
My sound card is a built in on my motherboard it is a ATI High Definition sound card.

I am using Windows 7 64 Bit.

And Biab 2010.5 Patch 304

Best regards
Michee
