It's not "my" tiktok in fact I never heard of that platform before someone passed that link to me. As such I know nothing about the quality of the sound.
navindra For me the entire point of this technology is for it to sound like the real performance...
My understanding is that, in the USA, S&S are sold to wealth people who do not play piano, as a status symbol and as an occasion to invite famous musicians to their house for playing at parties. During such events other wealth individuals are invited to the pretext to listen to the house concert, with the real goal of making friendships among the wealthy and perhaps business deals.
The player piano part is a plus for these people to have the instrument double down as an expensive gramophone.
The recording part was needed for S&S to become "independent" otherwise they would have needed to purchase Disklavier recordings (and more recently from other manufacturers, since it's becoming more common to have).
Let me repeat that the only reason I posted this is not to have any of such discussion, but instead to compare and contrast with our DIY sensorboard approaches.
JayKominek CyberGene I imagine how the technicians might have to also remove those boards when regulating the piano.
I think that sort of maintenance would tend towards justifying slightly larger modules. If you've got to take them out, then life is easier if they're not very tiny.
One thing I forgot to mention is that the ones so big are obviously good only for specific pianos, since the exact pitch between hammers or shank will be different and will not align. On the other hand, the pitch is approximately the same for all pianos, enough that your design with an option of 4 sensors per board strikes a very nice balance between not being too small (and all the corresponding problems of mounting, aligning, dropping, etc) and not being too large (and need to be custom for each instrument). Perhaps we may even go up to six, but we need to collect more stats wrt the variability from one action to another. Interest in collecting that data?
