Casio offers new arranger keyboards all the time.... Several new one every few years.. However, these ones are quite a lot more expensive...
Personally i would love to see 16 multipads and a touchscreen on every high end arranger. Its not the soundquallity that makes this instrument revolutionary, its the functionallity and interface... This instrument will show everyone that arranger functionallity has a place in a high end workstation, and thats something us arranger players have known for decades..
About the sound quallity, i think for an €800 instrument piano, dp, organ, strings, synth, pads, choirs are quite good... however, i still havent heard any convincing typicall arranger playing on the instrument, with typicall arranger styles and sounds like saxes, brass, winds woods... Also the drums definately lack punch so far. Weakest point in their sound engine seems to be the dsp, only 2 insert effects for 48 stereo channels..
Arrangers are a non typical US instrument, and espescially in Asia, south america, balkan, middle east are very popular with young and old... The US is a very different story, but worldwide arranger keyboards sell much better then synths or digital piano's
I think Casio is smart not aiming these instruments at the typical middel aged and above American arranger player.. I dont think they sound bad overall for an. €800 instrument and as Donny says, you get what you pay for... You cant expect the same quallity from this instrument as from a€3000 arranger..
I dont think however many of the typicall arranger players will have much use for all that added functionallity... How many of you are making extensive use of midiphrases in your multipads? How many of you are creating their own sounds with their arrangers? How many are creating their own styles and arrangements? How many are creating their own samples?
Well, thats the kind of instrument the MZ-X is... And Ralph Maten proofed to me that in the right hands it can sound top knotch...
