Sadly , couldn’t buy a Ketron, here in Aust. even if I wanted . Had an sd1, a long time back, from there it went downhill.
I think the only store that sells them over here , has a Ketron Audya 4 module and a Ketron sd3 for sale on their website, as far as I can tell, that’s it.
Guessing the brand is just not popular enough over here.🥲
