Reduced price for this keyboard, a lot of options, with Manual. I do not know how to use as workstation or the synthesizer, I have the Manual. I am selling on this price because as gift for a children is fantastic for to use as keyboard. For the other complex professional functions I ignore how to use or if that's work or not., But as keyboard is just perfect ,hundreds options of sounds, rhythms. I love but I do not have space, I need to downsize. I can lend the adaptor for you know how that's work but you need to buy one. Is something I use for other purpose at home.
