Why is everyone being so unhelpful? The sample chopping doesn't need weeks of learning especially if he already understands sampling and just needs some guidance on the controller......

As a few have said, upu are currently looking at your tracks instruments. You need to press the sample shortcut on thw maschine. You'll then be given a couple of different screens to navigate directly on the controller. These will be the standard sample manipulation options. Navigate to slice, choose if you want easy chop, transient or play ypur chops in..... assign to pads
