Ok here's my setup: I have an original DMC Ground Control V1.00, connected to a HEX, then connected to a Control Switcher (the one I have has black buttons).

Since The Ground Control V1.00 can only operate one single GCX-type expander, I have the HEX setup as the expander, and the Control Switcher is setup to respond to PC messages on midi channel 2.

The problem I have is that when I select a patch on the Control Switcher, one time out of maybe 10, it will have one of the following behaviors:
1: all four leds will flash a few times then all turn off. (the relays may or may not be set correctly as per the preset selected, it is inconsistent)
2: the proper preset leds will turn on for a fraction of a second then turn off (again, the relays may or may not be set correctly as per the preset selected, it is inconsistent)
3: the leds will show the wrong settings for the preset i selected (the relays switches are then also setup wrong)

BUT! if I disconnect the HEX and connect the Ground Control directly to the Control Switcher, it works perfectly, both in midi mode and in GCX-type mode.

I have no problem setting up and selecting presets on the HEX with the Ground Control.

The problem seems to be the midi out on the HEX.

any help would be appreciated.

thanks

Certainly shouldn't be happening but maybe a quick fix would be to go ahead run the Control Switcher ahead of the HEX in the MIDI Chain... or turn off the GCX in the Ground Control and operate both switchers via Program Change?

Is there any other MIDI gear in this setup?

There is no other midi gear in the setup.

I tried connecting the Control Switcher first in the chain, it did work, but since the Hex is on my pedalboard, and the Control Switcher is near my amp it wasn`t a viable option.

Setting both units to respond to midi didn't work with the Hex first in the chain. The same problem remained.

What did work was setting the Hex to midi, and the Control Switcher to respond to GCX messages. This setup suits me just fine.

All is well now, thanks!
