«  WAY ... »

already said very easy to use even if you never bought a synth, arranger, keyboard or any other, because there are very few of Other Features.
"Effects" are completely invalid. Sounds: there are mass (480 and dust), but few are of good quality. There are few drum kits, not terrible.
The sounds are somewhat varied, guitars and strings do not sound good.
The bass is not bad, synths leads are nil, the pads are not bad and fall are excellent, the keybord is good.
Apart from that, there are "styles" (ready-made drum beats) but varied enough that do not sound good to my taste.
There are also some "songs" (ready-made demo tracks).
The last point: The record.
Completely void for those who want to save, since there are at least 100 tracks, but we can not bring 2 tracks, or export!
So if you want to save just a piano melody, for example, that's all you can do.

OVERALL OPINION

It's been 6 years that I have, and I find this very average keyboard ...
Various sounds bad but, no effects ...
Short, simple keyboard, but not the height for those who want to do something pro.

on the other hand, if for example piano lessons, it is largely good.
