Hi Lou,

I have installed the SD-1 Rel.4.0 without problems.
The sounds are more clean, without noises, specifically the eletr. pianos, saxes
and organs (the Piano is amazing).
Till now I detect only a small problem, easy to solve (see my comments: “AJ help Miller 4.0……”, 02/27/2003) .
The great advantage of this keyboard is the facility to load the styles and sound parameters of rel.3.0 for rel.4.0 and vice-versa.
I love this keyboard.
