EXS 24 Logic Sampler Users Group

hi -

i am almost afraid to ask, but i have looked for the answer to no avail, 
and must come here for help. apologies if i have overlooked something 
staring me in the face.

with a song playing (lamg 4.5.1), when i push "stop" in logic everything 
politely stops playing except for the exs, which proceeds merrily along, 
probably forever if i did not arm "record", which stops it immediately. i 
am at wits end,  and clearly i have no good solution at hand. 

does anyone know what to do to make the exs stop when it should?

thanks,
bunk
