Digital Piano 88-key hammer
8 sounds (three pianos, a harpsichord, a vibraphone, a clave, electric piano 2)
chorus + tremolo adjustable (speed, DEHP)
Midi in out thru
Can transmit on two MIDI channels simultaneously across the keyboard, or split at any point
mono or stereo output
Atention if you use it as master keyboard, there is no pitch bend and modulation wheel.
sustain pedal jack (supplied)
Quite heavy to carry around (special muscle!)
RD300 = 88 notes
RD250 = 76 marks
P330 = expendeur version

UTILIZATION

The touch keyboard is not bad (better than the yam, unless the korg, to my taste!)
The buttons are very solid and are not afraid of a Jerry Lee Lewis unleashed.
You have to adapt to the onset of sustain with the pedal for those who have used the acoustic piano (sometimes annoying)
Ultra easy to use
Very efficient in master keyboard (two midi channels, split keyboard, separate control volumes)

SOUNDS

To the sound is a bit poor (8 total) but for the time it was not bad
The sounds of acoustic piano and electric are correct but you can not hack (no equalizer)
The "piano3" and "elec.piano a" very typical 80 years, we immediately reconnaita these sounds on a lot of records of the time.
Just a brightness setting a bit limited
The sound of vibraphone sucks
The chorus very effective
Great for the style tremolo rhodes

OVERALL OPINION

I have since 1989.
I'm very happy especially as master keyboard
The sound is really the misery compared to what we did today
In 89 it was worth 13 000f. The price / quality ratio for time was excellent.
Today it can be very interesting opportunity as master keyboard
