BobF,
I'm hoping one or more of my thoughts might help.
Have you checked Tascam's website to see if you are using the correct Asio driver for the version of Windows you have on your computer?
Yes. Verified by a number of other applications, including BiaB 2016
Does your Tascam driver give you the ability to select bit depth? BiaB and RealBand work with 16 bit depth. Perhaps there is an issue converting the input from 24 to 16 bit.
Same question concerning the Asio driver setting for sample rate. BiaB and RB use 44.1Khz sampling so any other setting must be converted.
44.1/16 is configured and working correctly for BiaB'16. I use 44.1K in my DAW apps as well.
While BiaB and RB can convert audio, it's additional steps and increases the potential for crashes. I'm trying to come up with things that will allow RB to get up and running until PG Music can find and repair the underlying issue.
Thanks for the ideas. I can't get far enough along with RB to verify the SR/depth settings, but I can run BiaB, verify the settings, then exit and start RB. 44.1/16 are the setting I have in Windows as well, so there isn't anything that should be changing them in between.
OK ... while typing my reply I got the idea that RB might be crashing due to droput (too small of a sample buffer). I normally run the interface with a 64 sample buffer. I just cranked it up to 512 and tried with RB again and it took the config without crashing.
So there are two things left to do:
me: see how low I can go with sample buffer size with RB without dropouts
PG: make RB handle dropouts in a more elegant way

Sound right?
Thanks again
