According to Yamaha website, "For the more serious musician in your life, start them off right with the DGX205. It features 76 keys, double the power of the next model down and a professional pitch bend wheel for more expressive playing of brass and string instruments. The larger keyboard, important for professionals, is also valuable for aspiring musicians. In fact many music teachers encourage new students to get a keyboard that will grow with their needs. In addition, we've beefed up the "Yamaha Education Suite" (Y.E.S.) found on previous models with a new interactive version, Version IV, which includes "Your Tempo" and "Repeat & Learn" modes. The keyboard comes with 30 pre-loaded songs, Flash ROM internal storage for adding more, and 70 additional selections on an included CD-ROM. Simply connect the keyboard to your computer via the convenient USB connector and transfer songs to the keyboard for learning or listening. And for recording your own songs, the DGX205 has a built-in multi track sequencer and can store up to five performances at a time. Finally, performance assistant technology allows you to play along with songs and not make a mistake – even if you're a complete beginner!"
