user interface : unimportant. there`s nothing to tweak.
sound : its not a wurli or a rhodes ore vintage at all. also not a dx 7 like one. but the sound is wide and very hifi like.reminds me to 80`s ballads.the release is a little too long for me, so its not usable for staccato or funk or faster groovy music.
features : none.
docs : unimportant because not needed. there is nothing to tweak at all.
presets : none.what you hear is what you get.
support : never needed.
value for money : exellent, if one might find it useful. i personally would not recommend it. to many alternatives by sampling cds and so on.nothing you cannot find anywhere else.
