Hi Christian,

Don't be lured into the Audya because of it's live sounds. This keyboard is unreliable, unsupported, and over-priced. I had two and returned both; Audya4 and Audya5. I strongly urge you to select another offering.
If you don't want to take my word for it, do your research in the Ketron Forum on this site. Do a search.
Best of luck with your decision.
