Thanks, that worked.
I just don't understand why looping is under "Record" rather than just a button on each track control board on the left.
That would be so cool, just being able to loop the tracks you want and mute the others.
I cannot get MixPad to loop an .mp3 or .wav file. I looked it up in "Help", but MixPad help is about useless and there's not anything that tells me how to actually get a loop to work.
