I seem to be missing something. I have read the manual but don't seem to be doing this right. After I assign track one to VEP and connect, then assign a new track with an Event Input to the connected instance, add the i/o plugin and bypass it at first I get sound but if I record some notes, or do anything all I get is silence and I have to go back to the original track with the VEP instance plugin to activate sound again. The i/o plugin doesn't seem to have any effect on this.
What am I doing wrong? Mac Pro, 10.6.8, Logic 9.1.5 64bit.
