Reply to Tracks getting "stuck" and looping options

Hi Everyone,

I have been using the s4 for about 6 months now, and mostly have nothing but positive things to say about it. I have run into a few issues though and have a couple of questions I'm hoping someone can help answer.

-Sometimes a track won't play and I have to "push" the jog wheel to get it going. This is a pain and sometimes takes a few tries. I notice that when I press the "search" button, the track may start to play, but when I exit the search screen it stops. Is this some sort of glitch, or is this some setting I can turn off?

-I'd like to be able to toggle the "loop active" button on the s4... I can turn loops off by pressing in the loop wheel, but I can't turn them on without the loop wheel placing a loop whenever I press it. Is there a setting where I can change this?

Thanks in advance for the help making this awesome controller all the more awesome!

-Ryan
