EXS 24 Logic Sampler Users Group

Does anyone know if and how I could set up a logic
environment so that my midi keyboard can trigger
samples on the EXS24II where one keypress will trigger
a sample to play until another key press stops it? 
I basically want to set up a system where in a live
situation I can trigger loops to play continuously
without having to use masking tape to hold the keys
down. 
Does that make sense or am I talking gibberish? 

Many thanks 


JF
