I just got the spider jam from Christmas so I am brand new with it. I was laying down some bass lines to a drum track and saving them to the internal memory. I haven't gotten and sd chip yet. The first couple went ok but when I got to the 4th one i saved it as recording 4. when I went back to find it there were only 3 loops showing and the most current one over wrote number three. I'm a little confused. I know you only have 25 minutes or so of recording time just using the amp and my loops were only 3 minutes or so each. Can you only save 3 recording to the internal memory or what am I doing wrong? Thanks for any insights. It's probably me. I'm not getting any brighter with age..Thanks  David
