Troubles with CC1 using Garritan sounds

Hi, I'm making a mock-up of my new piece for Concert band, using EWQLSO for flûte, oboe, bassoon, brass and perc, and Garritan CoMB for clarinets ans saxes. I'm expecting troubles with the 1st clarinet part which dosen't want to suit my CC1 events ... I drew all my CC1 events in the piano roll, controled them in the event view. For example, the clarinet is finishing a phrase, I made a decrescendo finishing with CC1 value as 50, and 10 bars later, the clarinet should play louder, around 100, but nothing occurs. (I have inserted a CC1 event with value as 100 !). If I open Garritan synth rack during playback, I can see that nothing moves in the 1st clarinet channel, whereas the Eb clarinet is moving according to the CC1 line ... Don't understand. Would it be that somewhere in my file, there would be a bad CC1 message annoying ? Can't find it ! I attach the piano roll of the 1st clarinet part, because I saw that two colors were employed, very stange because the part should only be orange. At the beginning I can see some pink. http://www.alexandrecarlin.com/CC1-problem.png Anyone would have an issue ? Thanks very much. Alex (from France)
