a: I would set a4 then tune piano as usual. You can always check the inharmonicity of the synthesizer with your rct but I think that you will find that they are different from a piano. I would bet that the synthesizer had a slightly unequal temperament as well. You won't be able to change the inharmonicity of the piano so equal temperament is the only answer in my opinion. 2: If the two pianos are equal size and the scaling is close this could be close enough. But if they are different you may find a nice tuning on one piano and quiet 5ths, fast 4ths, noisy octaves, unequal progression of 3ds and other fast beating intervals on the other piano. I have never used an rct. III: Try it and see if all of the intervals on the piano between the a's fit. If so then you have it.

Should I just make sure A4 matches and then tune the piano as normal, or do I need to determine precisely what temperament was used on the other instrument? In the case of a synthesizer, I would think the temperament might vary depending on the setting (for example "concert grand" might use a different temperament than "honky-tonk piano" or "harpsichord"). 2: Suppose I'm going to tune two pianos together, using RCT. It seems to me I could just calculate a tuning for one of the pianos, and then use the same tuning for both instruments (without recording the second piano). Any reason why this wouldn't work? III: Going back to part A, what if I used RCT to record the other instrument (let's say it's a synthesizer), and then used that to tune the piano? What I mean is, suppose I started up the program as I always do, but after clicking "record," suppose I played each of the A's on the synthesizer (instead of the A's on the piano) and then proceeded to tune the piano as usual. Would this work, or is this a crazy idea? Thanks, Paul Mulik _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives
