Voodoo Lab

Based on this post, it appears that I can switch GCX loops on or off with MIDI CC's: http://www.voodoolab.com/forum/viewtopic.php?f=9&t=3577

My question ...

Can I send MIDI CC's to GCX switcher without a GCP connected? I must use my iConnectMIDI4+ MIDI interface instead of my GCP (very long story and off topic).

Can I safely connect my iConnectMIDI4+ MIDI interface instead my GCP to the PEDAL connector on my GCX switcher?

Here's a link to the iConnectMIDI4+ - https://www.iconnectivity.com/products/ ... midi4plus/.

Why do I need to do this? ...

For our shows, I must automate loop management, sending midi controllers from an iPad app to my GCX.

My iPad is connected to an iConnectMIDI4+.

I need to connect the iConnectMIDI4+ MIDI OUT to the GCX PEDAL connection for the switcher to receive the MIDI CC's.

I have two versions of the GCX switcher, one labeled Digital Music and the other labeled Voodoo Labs. Are they both capable of accepting MIDI CC's to toggle loop state?

Thanks,
Chris

A GCX responds to MIDI Control Change messages 80 - 87 (for Latching type switching operation) or 104 - 111 (for Momentary type switching operation) on MIDI Channel 16.

If you will be controlling multiple GCX units you can either purchase custom firmware chips for GCX #2, #3, and #4 that set them to different Control Change messages, or if your controller allows it, send a MIDI SysEX string ( F0 00 00 07 01 08 10 F7 ) to the GCXs at every startup that accomplishes the same thing.

You MIDI Interface is most certainly capable of all of this, the limit would be whatever software you will be using and how they may want you to input this information.

I hope that helps!

Hi @JohnClark, It works! Very awesome.
Thanks for the quick response!
