Terry, Is there any clue in your statement that it is a 'grey market' piano, thus built for high humidity conditions? Are the pins perhaps a little looser in the block than they should be; or can anyone else suggest another problem caused by it being a 'grey market' import? Sorry if this is too obvious, i'm just thinking out loud.
