As far as I remember at least the Ketron SD1 is able to change tempi without changing the pitch of the sampled drum-loops.
Lionstracs started shipping the mediastation around october 2004, but still no professional video- or audio-demo's or a place where the X-76 can be demoed or tested.
(many members asked for it many many times!)

Sure..... good ideas/concepts need support and encouragement, but we truly need some 'prove' of the development so far. Only screenshots, promises and BAD (I repeat BAD) video demos played by non-prefessional musicians (e.g. the "pianist") make me think this company will not survive.

Domenik, please hire some good musicians, spend some money and show us what your equipment can do in a good video. (at least stereo, 128kbps and without tons of background noise)

I truly like to like the X-76
