For a digital, very realistic sounds for the classical instruments and the pipe organ sounds. Keys have a good solid feel to them (not like those cheap Fatar keyboards on many other instruments). It has 16 stops and 5 built-in organ sounds (plus 2 user loadable although Dexibell only has one available for download at the moment--a harmonium). Separate foot controllers can be purchased for expression, general crescendo, and damper (the damper does not operate on the pipe sounds but on piano and orchestra sounds). The layout is certainly with the organist in mind using tile stops, 3 divisions (2 manual and one pedal), and thumb pistons for memory presets. It will accept a midi pedal board, but without it, it uses a "bass coupler" on the lowest not on manual I. You can split the 2 manual divisions and even customize the split point or couple both together. The portability is fantastic. You can use a USB to record or to have MP3 backing tracks while you play. The keys are velocity sensitive on the non-organ sounds that not only volume but the tone also changes like a real instrument would when played harder. The trumpet and violin solo instruments are especially realistic sounding which says a lot. Key spacing is identical to an organ so you don't have to adjust your playing. Speakers can get quite loud but also has unbalanced output for stage. My only beef is that when changing settings or other operations like saving/restoring presets to a file on the USB or adjusting the touch, you need the manual so you know which buttons to hit--I just made a laminated cheat sheet that I keep with me. Other than that, I have no cons for what it is. Johannus organ company even uses it for thier "One" organ--they just load their own sounds and re-market it. Even besides the pipe sounds, the orchestral instruments alone are fantastic. This not a drawbar or "Hammond-like" organ, Dexibell has another model for that. This emulates a pipe organ.
