I struggled with my Etrac in the first couple of weeks, coming from an ATPro it was an unknown language. What helped me immensely was using the Bill S Trashy Park program. It's an extremely tight discrimination pattern, but it helped dilute the barrage of different sounds I wasn't used to hearing. In fact I still use an opened up version of this pattern today, but most of the time I run the Andy S Coin program. Good luck, it's a great machine.
