Dave, So essentially, the rails should be installed with A0 as the initial reference, regardless of the number of solenoids (88 is the norm)? The kit came from another dealer, and had been removed from an existing installation. The guy who removed it doesn't remember which note it lined up with (the unit was removed a year ago and the piano sold). The driver boards are intact, I've bench tested the unit, an and there are three solenoid rails, total = 81 solenoids. Unless there is a short rail hiding out there, that it, thats all. I haven't cut my slots yet, in anticipation of learning more about this admittedly questionable setup. The bench tests check out fine, with all tests that I can do. The way I install player systems is to remove the keybed from the piano and do my measuring and cutting outside of the instrument. I can also align the solenoids to the action, put on the legs and pedal lyre and adjust all parameters before re-installing the keybed in the piano. Fortunately, the Kawai keybed was not glued to the case, and easily removed. The other concern is that the client wants a Symphony module installed, and I want to make sure that the piano is playing the right pitch to the module. On the Baldwin setup, this is never an issue, but on this install, it would make some interesting harmonic effects if the piano is playing a semi-tone or two down from the sound card. Just for the record, I am not a factory certified PianoDisc installer, but a ConcertMaster installer, and this is a *dealer special* install for a client. I have PianoDisc experience, and have done extensive troubleshooting on existing installs, but not installed one from scratch. It's a bit more compact than the QRS solenoid engine, but definitely noisier (mind you, the unit dates from 1995) Thanks for the speedy reply, Rob Kiddell RPT Atonal Piano Service http://www.telusplanet.net/public/atonal/
