I have same experiences as Ulrich, and have had ever since I started using Real Tracks. I've reported it several times here publicly as well as in private in communications direct with PG support. The only response I ever got was that they could reproduce the problem. I recently upgraded my laptop from a Dell Inspiron 600 to a high end Sony Vaio running Windows 7 (so different OS and different soft-synth). Hoped that would fix it, but no joy. The Sony renders the Real Tracks in about one third the time and works flawlessly - except that the Conductor function still does not work properly.

Consider what you'd like to do in a "standards-based" gig, which is to sometimes (on the fly) add more middle choruses or jump to the last chorus at the end of the chorus being played. I don't have time at the moment for a long email, but it's easy to reproduce the condition by loading or creating a song with a standard 32 bar chorus with multiple repeats. Let it play past the first chorus then use Conductor to change the order of choruses - say maybe repeat a middle chorus. That usually seems to work -- until you come the end of the song -- which will not end properly. For instance if there's a tag ending the audio will play the tag, but the visual bar position indicator goes to the beginning the song. Then the song starts over, on it's own (all this makes me suspect software pointer problems).

I'm a ten-plus year, every-year faithfull upgrader and am a strong advocate for BIAB among all my friends and the people who come to the gigs I use it for. It's a great program, PG's a great company. Every upgrade I hope and look for this fix.

Thanks
