He played C2 while holding down C3, and the first partial sounded on C3. But when he held down C2, and played C1, the first partial wasn't there. Such was also the case in all the notes from A0 - B1. How can I tune that first octave to have the first partial sound on the octave above? I use a SATIII, using the program from Sanderson. Wim</blockquote> You cant really Wim. Two things to remember here, and I am sure you already have this in the back of your mind. The strength of individual partials is very much limited by the acousitic capablilities of the instrument, and below C3 the 1st partial begins to drop rather quickly in strength. Now the only way you could really reinforce the fundemental from the 2nd an octave below would be to tune them pure, or very nearly so, and you know in the bass that doenst work so well with regard to higher partials that are more readily heard. You can do things like this higher up, but this kind of priority is not built into the SAT, RCT, or other ETD's to my knowledge, so you have to set the ETD's manually to help you if you are going to use them in that fashion. Another point to be aware of is that its probably not all that desirable to strengthen the fundemental of very low notes too awfully much. At some point the instrument would begin to sound quite foreign to what we have come to know as piano sound. Just my take on it. RicB   -- Richard Brekne RPT, N.P.T.F.
