You've also discovered that, quite separate from how often the ideal unison appears on real pianos, your ears are far ahead of what you hands can accomplish. The curse of being human, that our perception is always pointing up our handiwork as being short of the mark. > FWIW, I have absolutely no trouble with the bass or the high treble, >it's that dang tenor section.

I think you need to be using the vernier adjust knob. Remember that a unison whose seventh partials are rolling @ 1/4 bps will have the fundamental turning over every 28 seconds. I'm assuming here that you can zero-beat individual partials. If you have access to the PTJ CD-ROM, look up an article entitled "Your Friend, the Unison". Bill Ballard RPT NH Chapter, P.T.G.
