Mark, Thanks for the offer, but I actually have dozens of pianos. The purpose of this test was to stress Specimen for Pete and provide some feedback. I used a MIDI file that produces a torrent of note events to see if Specimen could assemble rather large samples quickly and put them out to Jack. It worked great. (BTW, I should have said that the toylike Magix test used 16-bit, 48 Ksamples/sec, two-second-long samples, yet still failed very miserably --- as expected.) I'll actually use other MIDI files to test my large soundfonts --- more appropriate to the type of instrument I'm simulating. After passing this "speed test," I shouldn't see problems with the usual suspects, er files.
