EXS 24 Logic Sampler Users Group

hello,
 
 I jus upgraded my logic 5 to logic 6. Now, I am having a
 problems with logic pro. On esx, evp.... all the v-synth u can think
 of on my pro 6 has been acting kinda funny. Some keys have
 longer sustains than others. On some sounds, it would not stop
 at all. Funny thing is when i play evp, only C# and F has longer
 sustain. If i picked different rodes on EVP, only F# and D has
 sustain. It is similer to other synth.. as soon as i picked different
 sounds, different keys has unwanted sustains. Dose anyone
 exprience probs like this?
