David, As long as the three unisons of any given note are anywhere NEAR each other, you're fine with just sampling on one string. After all, all you're doing is a coarse tuning. That said, one piece of advice that will be helpful/beneficial is to tune the A440 to your fork before you take the AAAAA sample. That will get you a better pitch correction because the RCT can more accurately determine the amount of inharmonicity. HOWEVER, after you take the AAAAA sample, it's best to de-tune the AAAAA back to where they were prior to starting your pitch correction at A0. The RCT takes a moving 5-note average to determine overpull. If your A's are in up to pitch, you throw off the overpull on them, as well as the following 4 notes above. Rather than pulling a mute strip (which it doesn't sound like you use...) I just "tune" one A to a fifth below, then octaves from that. Paul On 3/1/07, David B.
