It's a Synthesizer, 61 keys (5 octaves) and there can vary from 5 octaves with mode "octave" key "Function".
There is possibility to connect the piano to a computer through a MIDI cable.
There are 487 Voice ("instruments) and 135 styles available. I do not think they are editable.
You can add effects to "Voice" including: Reverb, Sustain, Transpot, Tuning, Pan, Chorus and other
The sequencer is classic, you select the track to record, click on "rec" is played, then when we finished, click on "stop". To add an instrument, one after the other, must select another track and play anything until you want to hear the instrument

UTILIZATION

The general configuration is extremely simple, the manual is really useful to learn that backups and other options a bit special.
The effects are easy to do, just go under "Function", scroll through the options with two buttons and adjust the settings with the wheel.
The manual is very clear and sufficient to understand how the piano.

OVERALL OPINION

I use it for around 3.5 months.
What I like most is its ease of use and friendly interface.
This is the first model I tried.
The value for money is really good, I think.
Yes, I do it again this choice.
