Since I do not own a Ketron SD2 sound module :'( , I have tried using the the Drawbars button to make my life with vArranger2 simpler. I have tried to save some user sounds inside it, and it seems to work OK. I only intend to save Drawbar organ sounds inside it, nothing else. Even when I restart vArranger2, the user sounds are still there. Just thought I'd share this idea with everybody, hope you find it useful.
