Apparently those of the "one pass" use their SATs or RCTs in a pitch raise mode which, so I've heard, leaves the piano in decent shape when done. I have yet to actually experience this. I will openly admit that I do not overshoot when pitch raising. I simply use my SATII with a FAC from the piano and I go through once quickly up to pitch or with a slight rotation of the lights towards the sharp side. The second time through I have never found it to have dropped 25% to 30% drop in pitch. Maybe my rotation is more than slight...Anyway I can do a reasonable tuning in two passes sometimes a quick once more in the middle. The bass always stabilizes quickly. David I.
