I am having trouble finding and controlling where an audio file ends during export. I will go to export a small one second sample, for example, and the cursor keeps going on and on making a large file where there is no sound. I click on the keyboard 'goto end' key and it sends me to a measure hundreds of measures away from the beginning. Why? Can someone help me understand how to control where the end of a sound file is. How do I invoke the 'end' marker or change its location? Thanks.
