Hi Holger,
Notion only supports SE, i.e., articulations writen in the score can be mapped to SE samples. You can of course also use the Cube in Notion, but articulations aren't automatically mapped to samples in that case. I have been using Notion 6 together with the Cube for six months or so, and I write my own rules in Notion to link articulations to samples. It's a lot of work, but the advantage of writing one's own rules is that you have much more flexibility, and in the end the results are more satisfying than when using SE + the default Notion SE-rules.
