To play, the overall configuration is relatively simple, you press a button and there was a sound. It is however slightly baffled at first by the number of buttons and zippers, but you get done quickly. It's a bit more complex for recording and editing patches rhythm patterns, but it's still in the spirit of the 80s (pressing two or three buttons at once to save). Many combinations and variations. The manual is hard to find.
The organ sounds are great and varied (pipes, or style hammond combo) and can be edited via numerous drawbars, the vibrato is effective and of good quality, the strings sound more analog, but it is not a default, they are terrible (style Pink Floyd, Vangelis, ...), sounds "solo" is more anecdotal but some remain available and quite original. It remains in a range of sounds fairly standard (this is an organ, although comprehensive for the time) but I find rendering much hotter than most of the organs present.
I use it for five years and I do not think I'll never part. The sound is really good.
The pros: the sounds of organ and strings, the patch users to record the positions of the drawbars, noon, multi-timbralité, the separate outputs.
Cons: weight, rhythmic sounds (typed, 80 years, gender tr707, but is it a fault). It is not cheap (I saw one at 800 euros last year) but justified given the quality.
