With numerous suggestions and tips from jford, I arrived at a solution that enables low-latency input, monitoring and output to a mono track. The Fast Track ASIO driver worked properly with the old model Fast Track, I didn't use ASIO4ALL at all.

My old Fast Track model sends input signals to the right stereo channel, while RealBand defaults to the left. Changing that enabled mono track recording. This was huge for me.

What started out as an ASIO4ALL question, was solved by the use of the approved driver, and figuring out where to capture inputs. Thanks again to jford and to all that chimed in on this.

I learned a lot.
