Two more things:

Mac, I checked the output setting on the Dell. It was 67%. I raised it to 100% but in this instance, it made no audible difference other than loudness. When I turned the mixer gain down to compensate, it sounded exactly as it did originally. In my case, this factor doesn't seem to affect the tone or EQ.

Tony, I tried adjusting the pan setting on the piano sound to both the minimum and then the maximum settings (all the way left and then all the way right)but it made very little (if any) difference in the sound. So I don't think there is any stereo cancellation going on.

I also experimented with the tone setting of the piano track; changing the setting made an audible difference, but I don't think it helped with what I'm hearing.

I'm starting to wonder if maybe I'm just so used to hearing the Coyote software midi piano that the RealTracks sounds "wrong" just because it's different. It's funny, though, I don't ever think that when I'm listening to a recording of a real piano on the same sound system or any other. (My midi piano sound is now Coyote rather than Roland/VST as I said earlier; I'm not sure when that changed.)

I haven't been watching the forum much in the last year or so until I made the change to use RealTracks last month; has no one else ever commented about this? Am I just interpreting what I am hearing differently than I should? Why does the piano sound okay on my laptop's little speakers but not on the Bose, even though everything else sounds great on the Bose?
