A normal keyboard has a real disadvantage for pianists: The keys are much too small. This keyboard has keys in normal piano width, ie about 2.2 cm. They are about 14 cm long, making it about 1 cm shorter than the buttons on the 100 year old piano my parents. Say: It feels really just how a real piano (except for the ivory keys on old instruments). The keyboard runs over 4 octaves, you can still set a higher or lower, has a total of 6 octaves. The keyboard has no built-in speakers, it only works with the included software and computer. But then you have not only a keyboard, but a complete recording studio. Software: The software offers countless sound samples and the opportunity for free downloading much more. Above all, it offers a lot of instruments from the classical piano on stringed instruments to the orchestra. The sound can be changed from a small room up to a cathedral. Operation is intuitive even for beginners. Much you have to simply try to test it. Of course you can record everything you play. After that you can then mix multiple recordings together. Even videos can integrate and back them with texts. Conclusion: In the long-term test will certainly discovered more features, but in advance I want to convey before my first impression.
