Dear Bernie we all love Kerton sound but it is not worth it if you cant play what you need this is not big problem this is huge problem all of my music Based on samples in the Drums Including the right hand sounds if you think about it for me the SD9 or the AUDYA or the SD7 are all the same there is no sampler the sampler make the difference I had the Audya 76 for years just siting and waiting for the sampler finally I gave up... and my Favourite Word from Ketron is "soon" 9 years this is soon
