My journey with Ketron got a brutal stop after they announced Audya..
Date for arrival was set, I sold my SD1 to be ready for the new 'wondermachine', but delays after delays after delays the Ketron way ....
Got tired of endless waiting, bought a G-70, the rest is history.

That said, Ketron products sounds great, SD9 looks promising, but for me the next addition will be Korg PA?X-76.....
