Concert Strings 2 keyswitch issues

[cjtrag]

I recently purchased Concert Strings 2 and I'm having problems with some of the keyswitched instruments. So far, it seems to mostly be with the different cello instruments. Whenever I try and use the keyswitch version, the instrument will only play the initial attack and will not sustain at all. It's as if it is always playing detache. When I press the different keyswitches, it changes the sound of the attack, but it still does not sustain. However, the non key switched instruments (Cello Solo -adagio, for instance) work just fine. I'm using the EXS24 version on Logic Pro X.
