Assuming the same action parts are used on both models, should the strike point be reduced by the same ratio as the string length? Anything else I should be adjusting?
Hello John,
I would strive to maintain the strike points at the same places / ratios they are with the larger piano. This is what is done in most real pianos. If you were to play a 9' (270cm) grand, you would notice the hammers are noticeably farther away from the keyboard than what you are used to seeing on a baby grand -- that is because the manufacturer is maintaining a similar strike point ratio to the length of the longest strings.
On the other hand ...
Feel free to move the strike point slider, as you can always return it to its default setting. As you move the slider towards higher ratios, this means the hammer is striking closer to the front of the piano, nearer to where the front of the string is fastened. You will hear a series of more pronounced harmonics, at which at least some of which do not sound very pianolike. If you were to reduce the slider position ratio (say, to about 4:1), you will hear correspondingly fewer harmonics.
If you do decide to experiment with the strike point slider, please feel free to report what you have found!
Cheers,
Joe
