Hey,
First off, I am in no way an expert in this area. Just want to help anyway I can and possibly extract any info other members may be able to use to help you further.
I also own a Edirol PCR 300 and I have the same same settings you have decribed above and all seems to work. So that doesnt look like the issue. So you can strike that off the list :)
What exactly are your problems. Does it control the start/stop timeline etc when you Dynamic Mapp?
