Thanks for the reply, scook. I don't know if there's a setting that is preventing me from seeing Jamstix as a midi source or what, but when I try to set SD's MIDI input to Jamstix, all I see from Jamstix is audio outs, but no midi out. I've tried your steps, and then tried from the Jamstix manual, but try as I might, I'm not seeing Jamstix as a midi out. I'm out of options. In Reaper, all you do is load jamstix and set it up for midi out, then load SD right below it. I've used SONAR/Cakewalk for a while, and really want to stay with it, but I'd ALSO like to be able to use Jamstix to drive SD.
