The Ketron distributor in the USA is now sold out of SD1 keyboards and I've been told that the next batch coming will be the SD1plus which was shown at the Frankfurt Germany Music Show. I don't know what the changes will be but I'm looking foward to finding out soon. Hopefully, we should see these in a few weeks.
