You can get around the tail of the sample getting mixed with the next slice by creating a doubled slice, so for 8 slices that have been doubled, set the grid to 16 and choose odd numbers.
e.g.
However, this doesn’t fix the bug of the DT2 that has so far kept me using the DT1 until we get a firmware update to fix, and that is the sample trigger click on every damn trig of a sample, it happens on most of the stock samples too, its an audible pop, most noticeable when using the slice grid, but its on one shots too. (If you put that WT Morph Classic into a slice grid, you’ll hear the click at the start of each trig on that too).
