MEDIASTATION is good thing. I'm having one X76. Styles are better then in more keyboards as I tried. They are also balanced. You will not have a lot of work to start. But if you want something yours, you can open your mind here more as in other keyboards. You can load what you want. You can edit what you want. Also you can do your own style or song in Rosgarden (program is working in same way as CUBASE SX or CAKWALK or SONOR)
All is so simple and in one board. That is main thing. You can plug in also external big screen and you can work as with computer and playing a lot of things on (e.g. KARAOKE). You can do really what you want, but you must always thing with head.
B4 is well balanced sounds are standardized and same value as other things on keyboard. People of this company are really working for future. Open sources keyboards are good thing and you are free with your fresh ideas.

Best regards and lot of good music.
