Slice points are wrong if you have a not zero start point

[JonathanTaquet]

I recently noticed that the slices point addresses of the electribe seems to be relative to the start point.
The editor is currently addressing slices from the beginning of the sample, not from the start point...
So if start point is not zero, slices of the editor will not be properly positioned.

I will correct it as soon as possible.

This should be fixed with commit 6dd89aa
