I bought this one and I am digging it...
It has a ton of sounds that Jordan uses in his Dream Theater gig...
Still figuring out how to maximize it's use but already been inspired by the sounds..
there are 4 sound banks that are active at once... You can blend 3 at a time...that is damn cool ..the 4 is on the lower keyboard or you can play these pads on it that have pre recorded chords ( that you can erase and customize)
Jordan is a beast so his demos above will illustrate what it does much better than anything I can post...but I am planning on using these sounds on some tracks in the near future.
