It sounds like you purchased a U1SG 48" Silent upright piano. This is a very nice Silent Piano. The piano sample in the SG series of Yamaha Silent Pianos (grand and upright) is not the same as the sample in the Mark IV Disklavier. The SG sample is a much newer sample and to me, sounds better than the sample in the Disklavier. I don't know what problems you are having with the sustain pedal of your piano, but your dealer's technician should be able to adjust it to correct any problem it has.

Hi,
I just joined the group. I also just purchased a Yamaha UGS1 (silent grand). Does anyone know if the 9-foot concert grand samples are the same that are loaded onto current disklaviers? I am trying to figure out if my hardware is buggy because I experience some apparent problems with the sustain pedal. The easiest way to test this would be to listen to another UGS1 and see if they are the same, but piano stores virtually never have them in stock (special order only). Thus, if the samples were the same as those on the disklavier, I could at least compare to an disklavier, which often ARE in stock.
Thanks.
