Hi, I have a DL4 and am considering getting a JM4, but I have two questions that I can't find answers to.

Is it possible with the JM4 to go from recording directly to overdubbing, the way you can on the DL4 by hitting the far left button while recording?  Or, do you have to hit record, play a loop, hit a button to stop recording (going into play mode), and then hit a button again to start overdubbing?  The ability to start overdubbing immediately (without the delay/gap you get from having to hit record again) from the initial record is essential for what I'd use the pedal for, so this is a crucial question for me.  I have a different looper similar to the JM4 and the worst feature for me is the inability to do just this.

Also, can you save and recall loops if you have the SD card?  For example, can I create a loop, save it, and then load and play it in a live setting?

Thanks a lot.
