I have recently purchased a Helix LT and while I love the sounds it produces and I love the product in general, I mainly wanted it for recording.
My current setup is PC > Helix via USB > speakers via XLR.
In global settings under "USB In 1/2 Destination" if I have it set to XLR, I will hear the music and a live sound of my guitar. The issue is with the live sound of my guitar, there is a very, very slight delay which is very annoying. The recorded guitar does not have this delay which leads me to believe it is not a recording issue but an issue with the Helix via USB.
If I change the above said setting to 1/4", it will not output the recorded sounds from my computer however the live guitar will not have any delay, however I will be able to record with the signal (which doesn't help if I can't hear what I'm playing to.
Any help is greatly appreciated! :)
