Dreamer,

Every one to his taste ,but in all the keyboards I have had over the years , the best sax to me is the BLOWSAX from the Solton MS keyboards. I was shocked to find out it had been omitted from the SD-1 internal sounds, but as Henry already pointed out this sax, or virtually the same one, has been included on the harddisk soundfile. (as well as the outstanding musette/accordeon sound, also dating back to the years of the MS series).
However having said all that I seem to recall that the breathy sax on e.g. the PSR9000 is also very worthwhile, and ,like I mentioned before on so many occasions, there's nothing stopping anyone from running to the nearest sax player he knows and sampling the 'perfect' sax, THAT'S WHY THEY HAVE INCLUDED SAMPLING ON ALMOST EVERY TOPRANGE KEYBOARD these days. But like I said, the solton blowsax would be among the finest sax samples that I know of..........

saluti !!!!
