I am not quite sure what you are after, but if you are interested, I have listed and used the Sysex for the basic Chorus, Reverb and Delay MIDI effects for the KETRON SD2. These Sysex codes can be copied easily to the Sysex Window in RB.

Again, if you after the Patch Map for the Ketron, I can oblige.

PM me and I will send you the relevant folders with instructions for use.
