I have just switched over to Sonar X3 and was going through some old compositions and decided to take the claves out of TTS-1 and use the JABB claves (they are under Notation>08 Drums and Percussion>Percussion>03 Blocks>n-Clave). When I select them, the keyboard at the bottom of Aria player is completely grayed out, which I believe indicates that there are no playable notes. Does anyone else have this problem? I realize it probably isn't a real common instrument. I've never had this happen with any instrument before. Could it be that the playable notes are either above or below the range of the Aria keyboard? I have looked in the JABB manual, and it makes no mention of anything different.
