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. Havent gotten around to it yet as I rely so much on my ears that a generic version has sufficed... but got to dinking around and have a nice solution for any of you who are interested. Heres what you do : First go into the partial table and set all partials from A1 to E6 to the 3rd partial. Then set your tuning priorities to 6:3 for the bass and 3:1 for the treble. Then set the thing do fully automatic. Sample A1, D2, A2, D3, A3, D4, A4, D5, A5, and D6 for inharmonicity. Check your inharmonicity constants table so that there are no other notes in it then these. Thats about it. You should see that the bottom tuning deviation curve is pretty much flat. When tuning, I always tune 3 notes for notes D3 to D4. Namely the octave below and the 12th above in addition to the note on the display. From D4 upwards tune the 12th above in addition to the note on display and check the octave below until I hit A4. From there up its just the note on the display and the 12th above. This allows for an overlapping check for all notes from A4 upwards as I've already tuned them referencing the 12th below. Since tunelab calculates a pure 12th curve there will be no real difference in target frequencies. I finish off the lowest bass octave by tuning G#1 downwards with octave above on the display, finally checking with the actual note on the display. Cheers RicB
