Well, I THOUGHT I figured it out.
I poked around these forums about how to upload .hlx files, and somebody said "you can just drag and drop them in HX Edit"...
and I said to myself "I can definitely figure that out"
and I bought presets (.hlx files) from Rick Beato, Steve Cook, and Nick Hill... via HX Edit I got them loaded into the LT under "User 1", I can see them in the LT, I can choose them...
It LOOKS LIKE it should work...
then I plug in the bass...
and choose one of the presets I bought... make sure it looks right... fiddle with the volume...
Nothing.
Nada.
the Helix LT is not passing any sound through to the bass.
I choose another one of the presets I bought. Nothing.
I try the factory bass presets, which I found by uploading purchased ones... okay, I'm starting to figure out how to navigate around, but still no sound.
I have the 1/4" cable from the bass coming into the LT's "Guitar In"
I have a 1/4" cable from the LT to the amp from "1/4" Out Left/Mono"
When I skip the LT and go straight from the bass to the amp with one cable, I DO have sound.
It LOOKS like the Helix LT should be "doing it's thing".
I can choose the .hlx files I bought... I recognize the names, and the place I loaded them...
But... nothing.
Not even any "hiss" is passing through to the amp.
For any/all presets I choose.
Silence.
Is there an easy way to "brick" a Helix LT by... I dunno... turning it on wrong?
Or turning it off wrong after using HX Edit?
Maybe important to note...
After I configured it in HX Edit on the kitchen table, I moved it to the foyer to plug in...
When I turned it on it went through a long process to "rebuild presets".
????
But after that, I see and choose both the presets I bought and loaded, and also the Factory presets, and neither works.
Before I figured out how to buy, load, and choose presets from the market...
I was automatically chosen to a guitar preset which loads by default...
and I had sound there... the only not quite right thing was it was too loud, but not drastically so, if that blew up the LT, then the LT is a piece of kaka.
So figuring out how to navigate the LT... took me backwards...
I at least had sound when I had the bass going through a guitar preset.
So it seems like there's probably something very "BASIC" wrong... one wrong setting...
But I can't figure out what it is.
I verified my inputs and outputs are set to "Instrument", not "Line".
