This is MAJOR news. I have it officially from AJ that the SD9 is NOT the Audya replacement and also NOT the Ketron flagship.
The SD9 Pro is the professional version of the SD series and in a unique class of it's own, offering unique features for customers who what to spend more time playing and less time editting and creating from scratch. Thanks to newer technology, Ketron has succeeded in creating a musical instrument that truly puts music ...the arrangement of music at the hands of you the musician ... and which requires no engineering or IT background to operate (as seems to be the case with many instruments being released these days).
Audya's deep editing tools, multiple outputs including SPDIF in/out and additional audio features such as parametric EQ on audio drums...etc puts it in a unique class of its own for those who love to dive in deep ....( but not necessarily ahead) of the SD9 Pro, which also has unique professional features like Launch Pad not found on Audya ...or any other keyboard to date!
Ketron's SD9 Pro is for those who want a professional sounding product without all the in depth "editors and menus" usually associated with one ...one that sounds professional out of the box, a product you can purchase at 3pm and be gigging with at 6pm that same day.
In my opinion, both the SD9 Pro and Audya are flagships (a company can have multiple flagship instruments) ...just for different consumers and in different categories.
