I can’t use gm800 as my sound card,i have multiple input and output
Sure you can use a GM-800 as a MG3Hex interface, I do this all the time.
I have two guitar inputs and two pairs of stereo outputs, so I can’t use the GM800 as my sound card.
The Hex PU signals come in via USB. You just need to connect some speakers to the outputs of the GM-800 and make the selections in the MG3 setup accordingly.
Can I use the Antelope Zeng Quadro as a sound card and then use the GLK5 to connect the MG3HEX?
I don’t think that this works.
Your input must come from the GM-800 and if you are on Mac you could select any other soundcard as output.
What do you mean by “GLK5”?
