hi Christian, myself like many others have had so many keyboards in the past that for me it is hard to keep track. Some of them have been dependable and some have not. Ive had many isues with Kurzweil but I still love the sounds. I have had my Audya for about 6 mo. or so and not a single glitch so far. turn it on in the morning and off at night almost every day. I've had about every yamaha keyboard since the Dx-7 and some I have liked and some not. The same goes with roland and Korg . I now have a Korg OASYS-76 , Kurzweil pc-3 , Yamaha Motif xs-6 and my favorite Ketron Audya 5. You just have to go for the sound that you like , the feel of the board , the styles etc. I go by my own research and not so much by what I hear because most are too product loyal. I am not a product loyal person. If its what I like and fits the bill then it's worth a try. I love all of my boards for what they do and my Audya -5 has made me really love playing again. Make your choice and have fun. OH! Audya-5 has 560 styles. The layout of the panel buttons are as good and simple as any of the rest. Be blessed and keep rockin!
