>The microphone, or the internal circuitry in the SAT can be at fault, but this is rare. The newer SAT's have better filter circuitry than some of the earlier ones. I have seen some (older) SAT's that have trouble reading the 4th partial of A4, A#4 and B4, which is very high (2 octaves up) weak, and unstable on some pianos. Reply: Interestingly enough, I have an *old* accutuner (serial #176) and newer one, to compare, and was having the problem that you've all talked about, only on the newer one (with the midi and all the gadgets). I probably would have lived with using an external mic, constantly moving the machine around, trying to strike notes harder or softer, etc. and gotten by; but comparing the new SAT with the old, I realized this was not a necessary evil and that something was going haywire with either the mic or the filter circuitry. It was the latter, and a quick trip in to Accutuner solved the problem and it works great, now. So that was my experience. . .good look to the rest of you. Bob Simmons RPT Calif.
