Ric, What's the difference between this approach, and just setting the octave styles to 3:1 12ths in both bass and treble? I've tuned this way. --Cy-- ABQ, NM ----- Original Message ----- From: "Richard Brekne" <ricb at pianostemmer.no> To: "Pianotech List" <pianotech at ptg.org>; <caut at ptg.org> Sent: Tuesday, March 25, 2008 3:58 AM Subject: Pocket PC Tunelab tuning > Hi folks. > > Finally got around to figuring out how to do a P-12 tuning custom sampled > for each individual piano using Pocket PC Tunelab.
