Voodoo Lab

Hi, I'm a happy owner of a DMC Ground Control (firmware 2.4) as well as a very happy owner of the extraordinary Ground Control Pro. I have a problem to solve, the DMC GC only sees one GCX looper switcher but only ONE!, so I can't add more GCX or other loop/switchers like HEX or GRX4. With the GCPro version I don't have this kind of problem. Any suggestions or help?
Thanks!

The original Ground Control needed a memory expansion chip installed in order to control multiple GCX units. We do still have these chips I believe... feel free to give us a call or write to info@voodoolab.com for the current pricing and availability.

Good Luck!

Forgive me man but the GC manual why it says the opposite?
http://voodoolab.com/manuals/gc_origv2manual.pdf

The Ground Control can control up to 4 GCXs to provide any combination of 32 audio loops and switches.
To control GCXs from your Ground Control, they must be enabled here.
After entering Setup mode, activate this function by pressing [EXPANDERS]. The display should read:
GCX-1 IS OFF
To enable the GCX, press [+/YES] to turn GCX #1 on. If you have more than one GCX, press [SELECT ∨] to access the next GCX. The display will show:
GCX-2 IS OFF
You can continue to enable GCXs #2 through #4.

Please look to page 23 under the heading "Controlling the GCX Guitar Audio Switcher"

Controlling the GCX Guitar Audio Switcher
The Ground Control is capable of controlling 4 GCX Guitar Audio Switchers for up to 32 loops. However, to control more than one you must have the memory upgrade. Before you can control any GCXs, you must enable them from Setup mode.

The part you found on Page 13 should probably have also indicated that you need a memory upgrade to enable more than one GCX for complete clarity... oops!

Congratulations! You are the first one I can recall to have found a slight error in a 20 year old manual! As a prize, I'll give you the chip at no charge! (NOTE: We may have to charge shipping depending on where in the world you are )

Are you serious or are you kidding me?
Will you give me the chip for free !?

Completely Serious!

I'll have someone contact you to get your shipping info and we'll get you up and running in no time!

p.s. With the Memory Upgrade will also be a updated v2.5 firmware chip. This will need to be used to ensure proper function with the memory chip we will be sending.

Wow! What can I say, thank you very much and I thank the whole Voodoo Lab team.
I'm your loyal customer, not by chance I'm the owner of:
1 DMC System Mix plus (very rare here in Italy)
1 GCP
1 DMC GC
1 GCX
3 Pedal Power Digital
3 Pedal Power Plus 2

Thanks again John.
