It sure does James, and I am very grateful for your simple and effective explanation.
Can you also go thru the SD2 sounds one by one without having to feed the nine digit midi number every time for every sound, or do you need a Midi masterkeyboard for that ?

I must say I have always been enthousiastic about both Korg and Ketron (Solton) but this ultra budget combination is really something.
Shortly I will also add a Behringer UMX49 small masterkeyboard and that should clinch it.
The Korg PAs are simply amazing keyboards and the PA-500 does absolute miracles in relation to its price tag. And the very least can be said for the Ketron SD2 module.
There is no accounting for tastes I know, but
I'll go for the "two K's " anytime..........
