GCX not powering the GCP

[drolaw]

I was hoping someone could help me troubleshoot why my GCX is not powering up the GCP using the midi cable. I have the midi cable connected to the Midi Out on the GCP into the pedal in on the GCX (Ground Control only).

I end up using the supplied power adapter to power the GCP and everything works fine but I have no luck powering up the GCP using the GCX. I did try different midi cables so I'm thinking something is wrong or huge user error on my part.

Any ideas? Suggestions?

It looks like I was using the wrong midi cable. Only 3 of the 5 pins were wired. Of course there are no guitar stores locally that carry what I need (all 5 pins wired).

Any suggestions on midi cable brands/model and where to get them?
