Totally agree with the comments above from “bsd512”, this is exactly the way I use Helix for re-amping in Logic Pro.
Although, I did once come across a guy who had problems using the re-amp setup.
When I asked if he had USB 7 set to guitar - he said yes.
Then he explained what he was doing, and it turned out that the reason he couldn’t record any signal was because he was using a Variax!
A guitar is a guitar, right?
Not when it’s a Variax!
Please tell us that you’re not using a Variax.
If you are, set the USB channel 7 to Variax.
