Claudio, First I would expect that you should not use the standard Grand Staff, but have separate keyboard staves. Then see if you can assign a different time signature on one stave. This is really interesting, and I wonder how the internal metronome would handle this. If I get time, I'll mess around with the concept.

But I'll try to remedy that situation. ----- Original Message ----- From: "Claudio Sacco" <cl.sacco@xxxxxxxx> To: <sib-access@xxxxxxxxxxxxx> Sent: Sunday, August 21, 2011 10:15 Subject: [Bulk] [sib-access] Piano with different time signature in both hands Hello For a musicXML experiment I want to write a two bar long piano part, where both hands have a different time signature. Something like you can find in Bach's Goldberg variation number 26. He writes 18 sixteenth for the right hand and 3 quarter for the left hand. Of course the bars of the right and left hand have the same length. But how can I change the time signature of the right or left hand without changing the other hand. If somebody can tell me, it doesn't matter what Sibelius version for this purpose.
