Problem solved! I opened the dxi/vst box selected the port/synth entered none, but then I opened options and clicked on save default settings. Apparently when I thought I was saving my Jabb3 patch set up for a particular file, I made it the default setting. Now, I know this is a global setting. I still could use a little explanation about the difference between assigning a dxi/vst to a port or a synth.Thanks...Bobby
