> Regarding KIO2 control, where can I find more info? You have to use the SWxx commands, where you simulate pressing a switch. There is no direct "Set KDSP2 bandwidth to xx Hz" comamnd for example. And to my knowledge there is no way to poll the K2 display to see what it is showing (which would then give you feedback on the KDSP2 state), although there may be and I just haven't found them... 73, Lyle KK7P
