I know a little bit about the MZ-X. there will be 2 models :
MZ-X300 and MZ-X500. Both have 128 note polyphony.
These products are to compete with the Yamaha PSRS770 keyboard. There will be more intro's, endings and variations. I was told that the quality of the drum kits and styles have been totally upgraded. I hope so! The instrument voices will have a type of articulation but I haven't heard this until I get to NAMM to know how the sounds compare to the Yamaha super articulation The MZ300 will have 4 sample pads and the 500 will have 16. Pads can be used for:
Sample Triggering
Drums
Effects, Instrument Articulations (Guitar Harmonic, Trumpet Fall�etc)
The sound development for the MZ-series has been a gigantic undertaking with the creating of new sounds and DSP effects to support them
Basses and Guitars:
Multiple acoustics, nylon string, steel string guitars, jazz guitars, even ukuleles.
Multiple Electric guitars including a variety of pickup positions
Many articulations: Harmonics, mutes, ghost notes, slides, fret noises and more
New Electric and acoustic basses
Drums: 3-8 velocity splits for some sounds for incredible realism and dynamics
Wind Instruments
Soprano / Alto / Tenor Sax
Clarinets
Monophonic mode for melodic playing
Electric Organs: Vox, Farfisa�
Accordion: Scandalli, Hohnor, Excelsior and more
New Drawbar Organ Mode with new Rotary Speaker Effects

The two MZ models will also have SAMPLE MEMORY for adding additional instruments.
