Who Is It For? If you are a beginner, who is keen to learn & play more of piano pieces, and would like to have several voices & accompaniments, and do not have the budget for an authentic 88-key keyboard, this can definitely fit the bill.
Intermediate players can also find this of use, as it comes with a 6-track recorder which you can use for recording your creations, has audio inputs for connecting an MP3 players so that you can play-along to your favorite tracks, and has USB midi port so that you can connect it to a computer and work with various music software.
If you're a beginner, you'll be amazed with what's on offer. Not only you get 2 little song books, the keyboard also has a song bank consisting of all the songs available in the book.
The songbooks of sheet music gives a brief introduction to piano and the basics such as fingering, notes, measures, abbreviations. and its not just in English but in several languages.
Then, it has 100 popular songs (sheet music) starting with the very simple songs (Twinkle Twinkle Little Star) to fairly advanced classical pieces (Nocturne op.9 no.2 by Chopin). For the classical pieces, the sheet doesn't include the entire classical piece, but shorter versions of about 3 or 4 pages. This is where the 76-keys will come in handy, as you'll definitely require more than 61 keys to play some of these songs.
You also get a few blank pages towards the end, which you can use to practice music theory, or to write your own compositions.
All these songs are also available on the keyboard as a song bank. You can listen to the song to get a feel of it, which makes learning to play them easier. The display also shows the notes of the song as it plays (and the notes that you press).
With so many ways to learn, you can even get started on your own without needing a teacher (first few months), and it will definitely keep a beginner occupied for a couple years!
It comes with powerful stereo speakers, and has a good built-in learning system that helps you to learn to play the built-in songs.
It also comes with several advanced functions such as auto-harmoniser, scale changer, USB, line input, and sequencer.
In spite of the 76 keys, it's quite portable, in case you have to take it to the school to practice with your band, or if you are going out of town.
