OK, first of all I must say a sampler couldn't possibly sound much better. Especially the filters sound wonderful.
Secondly I like the user interface a lot. Parameters are logically organized in one screen. The idea how the velocity and modwheel modulations are set within the sliders of the actual parameters is wonderful and compact.
LFO's and portamento settings are versatile. Combined pan/tremolo modulation by LFO sounds great although there seems to be a bug in that the LFO1 delay/decay doesn't apply in this particular case (what a shame!).
What is NOT great is that I wouldn't call this even a sample player (you can't even play .wav samples). It's merely soundfont and AKAI sample player (and AKAI import won't even import filter settings).
However, the most serious omission is the fact that you can't save .exs presets. You can save them as .fxp in Cubase, but this way you can't see these presets in the great flip menu. Oh NO! Do something to this Emagic!!
