I do not believe Ketron and Yamaha will jointly build an AK, but I do believe Ketron is working on the sequel to the SD1... and since this is primarily a Yamaha forum, they're looking for what specific Yammy features might be prioritized into that KB. Another example of how Ketron really pays attention to what AK players want, so continue to give a wish list, but we need to be realistic and not expect such a KB to be < 30 lbs or $4K.
In addition to several features already mentioned, and EZ mp3/audio incorporation, give it a killer B3 organ and Leslie rotor effects, like my B4. Now that would rock.
