The keyboard is 61 keys average quality (worse than the keyboard of the M1, better than DX7)
Pitch bend, modulation, portamento keys, solo, and transposes
All parameters are ditables in real time via a slider / paramtre
64 sounds possibility of extension housing rom / ram M256
internal effects
Polyphony, but I do not know limit (24 I think)

UTILIZATION

Manuel suitable

SOUNDS

A HUGE MEGA BIG SOUND IN BREATHTAKING EVEN TODAY
The audio standard is 80/90 in this machine
Do not try ralistes acoustic sounds, it is somewhat in the spirit of D-50:
large tablecloths, sound synths ... but much more standard
You guessed it I'm a fan!
VLOC and aftertouch ok
You want the sound to Jump by Van Halen, and although I put a cot Alesis QSR, a Korg 01W, a Korg Trinity V3 + Moss, a Korg M1, a Yamaha Motif, a Roland D-50, a Roland XP-80 ... Well there is no photo, it's JD, and far away ...... trs trs

OVERALL OPINION

Machine must!
Only BMOL, the polyphony, and cursors that would tend to age poorly, but the sound is so standard ...
DEFINITIONS A. It is the synth if I had to keep just one, it would be him!
Aside from the fact that it is not versatile.
