Please help me

Iam having a problem with my mpc. I will created a entire beat with my mpc and motif. It plays fine until I save it and come back to it. When ever I load it back up. The are pauses at the beginning or the middle of my loop and I was wondering what was causing it.

your original beat my be looping to another bar besides 1, which stays when you are using it, but maybe doesn't get saved?

Is there anything I can do, or how can I fix it

see if a bar has just silence, then delete just that bar.

Just guessing but it would appear that you are tweaking your samples in the paramater screen. Doing this and not saving it as a new program could be the problem. Unless you save the settings when you shut down all that tweaking is lost.
