EXS 24 Logic Sampler Users Group

Has anyone out there experienced hanging notes with the Akai Splendid Grand EXS
 instruments? It seems to only happen on certain notes. I deleted all of the
 groups in the 72M program and that seemed to fix the problem. Are groups even 
serving any function in these programs? Any other ideas/solutions to the problem?
 
 Thanks,
 
 Matt
