control 2 loops simultaneously with one instant access

Post by fournij »

Hi

I want to know if it's possible to control 2 loops (on / off simultaneously) with the same instant access button.

I have a stereo delay that feed two amp, it uses 2 loops and I want to turn it ON and OFF on both amp with the same instant access button.

thanks

There is a mod that can be done to the GCX that will allow you to switch the state of two loops with a single Control Change message. Write to info@voodoolab.com for more details on how to perform this mod or to have your GCX sent in to have this mod done.

We also offer a Stereo Upgrade board that will convert the GCX loops to Stereo using dual relays for each loop and TRS jacks for all 1/4" connections. A single Stereo Upgrade board will convert four GCX Loops to stereo. Two Stereo Upgrade boards will convert all eight GCX Loops to stereo.

Hi John, is this mod to the GCX (the one that allows it to switch two loops with a single ctrl change) compatible with the older Ground Control (with updated sw) or is it only doable with the GC pro?

Thanx

L.G.

It is a hardware mod to the GCX... it would be compatible with any controller that can control a GCX.

Interested in this.... the mod is only performed by Voodoolabs or it can be done by yourself? I'm asking because I live nowhere near Voodoolabs...
