Is there a way to import a beat, slice up and easily map with Halion4?

You cannot slice from within Halion 4 unfortunately. You can however slice from within your DAW and import that way, or import already sliced beats from say RX2 files etc. I am having issues importing and using home made RX2 files as seen in this thread I created:

I am hearing no feedback about it either, so am unsure what to say exactly.

It would be nice if you could import a beat and slice it from within Halion 4. Perhaps a feature request in store to ask Steinberg nicely for their thoughts on it?
