[chuck-users] Using LiSa w/o recording?

Hi List, I am playing around with the LiSa ugen and I am wondering: Is there any way to get data into it other than recording it (in realtime)? E.g. by loading a wav-file, or copying an existing Buffer? Please forgive me if I am overlooking something obvious :-) I am rather new to ChucK. TIA + Kind Regards, --lu
