MIDI cable

[llpcode]

1) Does the Eleven Rack have real 5-pin MIDI connections or just 5-pin with 3 active MIDI connections?

2) Using a Voodoo Labs Ground Control Pro - which cable (e.g., Brand and type) to use?

3) Could connecting a 5-Pin ACTIVE MIDI cable to an Eleven Rack cause malfunction or damage to the 11R?

Where did you purchase (Online) your MIDI cable from? (I am working in Shanghai, China - so I have to purchase online gear)

(PLEASE do not add different MIDI controllers to these questions)

copy and paste from the manual

1)The MIDI In and MIDI Out ports are standard
5-pin MIDI ports, each providing 16 channels of
MIDI input or output. These ports can interface
with a variety of MIDI devices.

Okay, no matter which MIDI phantom power-capable foot controller you have (be it the GC Pro, Rocktron, Bradshaw, Mario's stuff or any other that uses a real MIDI cable), they are designed so that power comes DOWN from a device providing power, TO the pedal, on the unused pins. Mario's and the GC Pro use 5 pin, where the Rocktron and Bradshaw stuff still use the older 7-pin standard.

However, if you plug an adapter directly into the pedal itself, I don't believe that it mults that voltage to those unused pins. Meaning, it shouldn't be sending voltage back up to the 11R from the pedal.

I'll have to see if I can find out for sure - I don't know because I built a box for myself that powers the GC Pro remotely from the 11R rack, and thus those hot pins never reach the 11R in the first place. Anything else I have that I plug the GC Pro or the MIDImate into phantom powers them (either my Bradshaw rig or my Mario switcher).

I'll see if I can find out for you, but I don't think it's a big deal. I have a bunch of old Tascam MIDI cables that are fully pinned that I use for gigging with phantom power (you have to love old Tascam cabling - they followed a spec, boy

Sean,

Are you saying your 11R powers the GC Pro right from the midi cable? I'd love this feature. I currently either have to power the pedal with the A/C adapater or have it powered by using my GCX audio switcher. It powers the GC Pro via midi but I really don't need the GCX with the 11R but have to keep it in my loop to power the GC Pro (i don't have a separate a/c adapter )

I don't know if this will work for you or not, but take a lok at this setup-

Please note, on this wire for those of you who are interested, the end that plugs into the pedal to provide power is 7 pin. It's been a while since I looked but I believe the "Midi Out" of the GC Pro is 5 pin which would not accept this wire although it may work great for other midi pedals. I actually have this wire from my Lexicon R1/TC Electronic G-Force days, worked very well.

Sean, what is the pinout in your solution. I would also like to have one cable less on floor.

I have 11R with GC Pro, but the adapter is for 120V and we have 230V in Norway.

fixed it, I found it in this thread:

Only the three normal pins go to the 11R. The power adapter only goes to the other two unused pins on the jack going to the GC Pro, and all 5 pins are connected to the GC Pro via a fully-pinned MIDI cable. Thus, the voltage from the adapter never touches the 11R side of the little box.

Make sense?

By the way Jerry, the GC Pro MIDI Out is 7-pin, but accepts both 5-pin and 7-pin phantom power coming into it - pretty much anything you throw at it should work. The 5-to-7-pin adapters were originally created to allow 7-pin Rocktron and Bradshaw controllers to work with the newer 5-pin phantom power spec the newer guys were moving to, not the other way around.

Hope that helps...
