10 appearances and still no trial date, excessive?

This is not totally unusual in New York courts.  Your attorney might have waived any speedy trial provisions with the hope of coming to some deal with the DA.  Conversely, the DA may have come without some vital piece of evidence or witness and the judge allowed them a continuance.  You need to ask your attorney to explain these delays to you, or if you are representing yourself, you need to make it clear to the judge that you do not understand why the case is going to be continued.
