for us pros on stage..what I love about Ketron arrangers like the Audya & my Midjay is that you can access and play all modes SIMULTANEOUSLY if needed. This is something you cannot do with most other arrangers,...this is imperative on stage when you are juggling between songs in different modes when using styles/smf/mp3/fx/...etc, it also creates no in between time and easier segways,......otherwise you have to use a laptop, tablet, etc.

Another Ketron arranger favorite feature for me was
Bass lock, & Drum lock, giving you so many more variations to create in style play also.
