There is pre and post buffer information in the .WAV file. This is what allows you to trim out on a loop you have just captured. To get rid of this data you must discard it by entering the a trim window by pressing trim once. Press and holding the trim button while in this window until the display reads "trim cut". then just press trim again and the buffer info is gone. I'm sorry to disappoint but there will still be silence at the beginning and end of the loop that you will have to trim. It is a standard .WAV file.

Thanks a lot, it's saved me a lot of headache/time. Makes me kind of mad though, as the Repeater was billed as something that would give you a raw .wav file for your editing pleasure. The ability to share files between the Repeater and my Mac was one of the main reasons I bought it over the EDP. Yet another dissipointment. I feel that Electrix should make good on it's claims and write a program (MAC and PC) that would make the conversion from Electrix .wav to standard .wav and back, and add apropreate files so the Repeater can use them again. It is what they advertised. Mark Sottilaro Tim Goodwin wrote: > I eventually want to compose loops in ACID and import them onto tracks in > Repeater to use in live applications.
