I had some time this morning to sit with the Mz-x500 and play it for about 30 minutes... I first tried out the styles and the wind/brass/wood cattegory of sounds.... I found both lacking in quallity compared to the psr970 and pa600. Both the styles i tried as well as the solo sounds missed dynamics and sounded like Roland pre G70 and yamaha pre SA acoustic sounds..
I also found that many of the styles are the same as the styles in the Casio px560.
Other sounds like piano, dp, strings(non solo), synths, where actually much much more convincing..
Some drumsets sounded quite good in the styles while others seemed to lack any form of punch..
The B3 emulation was quite good...
I however was most dissapointed with the keybed, it felt cluncky very light and i could move kesy quite easilly from left to right.. Doing Organ slides really hurt my hands as the keys where sharp, compared to the px560 keys (material and finishing) they where clearly low end... (I think the triple sensor action of the px-5s and px560s is actually quite good, and as said many pro players seem to agree, i still have to get used to the material they are made of, however people convinced me that when you have sweaty fingers, you will never want any other keys anymore)
Then finally i went down to the hex sounds, and they are clearly the bread and butter from this instrument...sadly it lacks some dsp power to make them sound even more convincing...
Finally i tried the pads, they are truely great, and feel like most other buttons high quallity... I tried to mix some phrases with full style accompaniment, but somehow the things i tried didnt give me the feel i get when for example using "Modern Country" on korg pa4x with "Grv Drum 1" and "Grv Dance 1" and "Guitar Country" These pads (phrases) can be used to make an allready gread style even more dynamic...
The pads i tried on the Mz-x worked well with a styledrum track, but not so good with a full arranger acompaniment style..
Kudos however go to Casio for ease of operation.. And the number of tools inside the box... But the product as a whole, lacks a lot from the quallity of typical arranger content.... It will however be a tool for creative minds all over the world to create their own stuff and music.. But out of the box playing a nice Samba with a muted trumpet (which didnt even sound like a trumpet al all) will not get many oohs and aahs from the audience...
However, for people playing in a band, there is enought quallity to do some decent selfcreated backings ...Also for the youth that wants to use this as a synth workstation, there is more then enough to keep them creative. And even selfcreated arranger styles could be cool...
But playing arranger straight out of the box, is definately not its strength..
