hmmmm had the rack, which had two extra banks and increased poly, otherwise the same sounds and they were excellent. every section was well represented, a rarity among workstations..... well, maybe not pads. ... however those were not bad by any stretch of the imagination. htey just were not as good as a tritons pads in my opinion .you get more bass sounds than you should ever need, and the "vintage" type keyboard instruments were the best of any workstation yet..... (organs, ep's, wide suitcase, etc....)
as far as the rest i do not know, as the rack does not include them. if the sequencer and sampling are not REALY needed i suggest you save your money and go with a rack (if you have another sequencer, which you do.... and sampling...) because it has increased poly, (128) synth features and even comes with its own pc sequencer, voice editor and librarian.
