I'm a newbie and am using Logic Express 7 and want to add a whistle sound to my song. Have search the web a little and browsed my sound sample library but could not found the right sound. Could I do it using the synth come from LE? I want the whistle sound when a steam engine train start to move. "We-we----Oo" that is the most common sound of a train that we should all familiar with. Alternately, anyone knows where can I purchase/download the sound file?
