The message sucks. There is no Options | MIDI Devices command. I had to drill down to Options-->Preferences-->MIDI Devices. There I moved Microsoft GS Wavetabe Synth to the top and the MIDI file plays in RealBand. It's still an acoustic piano sound. This is a flaw in BIAB. I'm not seeing Ukulele in that list of patches at all.
