Terry, Sorry it's taken so long to respond to this. I've been on 3 year-old boy-overload lately! I'm not sure if my information will help at all, because it really hasn't much to do with voicing. The problems I have in the killer octave in new pianos are related to tuning stability rather than tone(give them a couple of years, and the tonal weakness becomes more evident). Whether or not I do a pitch adjustment on a new piano(primarily of Asian origin, write me back offline and if you really want names), I ALWAYS go through that section twice. As per an e-mail exchange not long ago with Ron N., I have watched one spike/string in the tunelab graph drop radically as I pull a neigboring string up to pitch. While this instability is evident throughout most of the piano, it is markedly greater in the KO section. I whack these notes pretty hard before even putting a hammer to the pins. I realize this isn't what you were asking for, but I hope it helps a little. Dave Stahl ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
