Best bet is to take a loop, simple 4 beat loop, let it run a few times, press memory, press cue point 1 2 or 3. Then press the sampler button, press whichever cue point you stored it in, if you are playing live make sure you do so on beat or it will sound like a mish mosh, so long as the sampler button is lit it will play a seamless loop of the sample, you CANNOT store the loop/sample, what you can save into memory is the beginning cue point. When you have that sample in the cue point, if you hold down the memory button for 3 seconds it will store that cue point into memory. Now, when you power the unit off that cue point can be easily recalled by pressing memory when you insert the disc, if you are in continuous play mode, when you call up the cue point by pressing it, you will have to hit IN loop, otherwise when you hit cue, it will go back to the first track. By hitting cue, you set that cue point as your current active cue point. Play the song in your headphones and repeat the original process of looping and then follow the original instructions. . . . any more questions?
