Here is my method for creating beat slices in Cubase to create custom drum loops, drum replacement and other creative editing ideas. First, import the audio file that you'll be working with. In this example, I'm using an audio sample of the classic Drums and Bass "Amen Break".
Keep the sample editor open.
Keep in mind that Cubase will automatically cross-fade between any overlapping slices, saving you time.
If you wish to edit your slices to different note values, such as reducing a snare sample that is set to an 8th note region down to a 16th note, you will need to first change the Snap Type to "Grid", set Grid Type to "Use Quantize" and as your Quantize Preset choose the note value that you're reducing or expanding your slices to. When finished, change Snap Type back to "Events" so you can properly quantize your sliced regions with each other.
