Helix Effects, multiple paths and 7CM

[bcm27]

I have a duel amp pedal that has the ability to switch between either channels A and B, combine channels A and B into a single mono source, or do two completely separate split mono amps with either completely separate effects loops per channel or a single effects loop going to both channels. This is the Simplifier X by DS&M Humboldt a absolutely fantastic device.

 

What I am struggling with is setting up the HX Effects to take advantage of the two amps in a split signal path from a single source, aka the 7CM method (I can setup a 4CM perfectly fine with a mono source going into the amp in A||B mode). In the manual they have a picture using the HX Effects and it outputs to both left and right using two separate paths. However I cannot for the life of me split my signal chain into two separate paths. The best I can do is a Y split with the two effects loops panned left and right which works great for side B however side A is not outputting any audio and I get some signal crossover from B into A. 7CM_Clean Start.hlx

 

If anyone could tell me what I am doing wrong I would appreciate it! I am a new HX FX owner and I absolutely love this thing.

The way you did this only makes sense if you use both the L and the R outputs of the HX Effects (stereo use case or summing both channels later e.g. in an external mixer).

For a mono use case set the Mixer block's pan parameters to center.

 

For a stereo setup the preset looks fine.

So is what I am trying to do even possible? I took another peak at the  17A 4CM:Clean Start preset template that Line6 provides and I dont see how it would turn the FX loops in stereo without the feeds getting crossed. Is that why when I turn off both FX blocks I still get a very quiet signal through the FX loops of the amps because theyre wired to the the end of the line outputs for the HX FX?

 

I have the above image mimicked in my wiring I am unsure of how to set things into stereo like you described.

 

Helix Input L/Mono : Guitar

Helix Send 1 -> Amp Guitar Input B

Helix Return 1 -> Amp FX B Send

Helix Send 2 -> Amp Guitar Input A

Helix Return 2 -> Amp FX A Send

Helix Output L -> Amp FX B Return

Helix Output R -> Amp FX A Return

 

Once I fix the preset and cable routing I plan on putting the dirt pedals in front of the Amp Inputs for A & B.

To make sure: your goal is a template for the using MODE 1 (full parallel) of the SimplifierX with independent FX for both channels from the HX FX?

I ask because the simplest 7CM patch is to just a FX Loop L/R block. You can use stereo blocks in front or after the loop - that's all it takes. Only if you want different things to happen to both channels (things that differ from what stereo blocks already can do) you need the split approach.

 

There should be no crossfeed if you used the Mix block hard panned like in your image from the manual. Make sure to turn off MONO LOOP on the SimplifierX.

 

If you bypass the loops the signal goes from HX's input to OUT L/R without passing through the preamps of the Simplifier - hence the "very quiet signal". 

 

Your cabling is what I would have come up with, too. Looks right.

This is I believe what I have with this preset. I was playing around with the routing within the HX after I double checked my cables and I believe this is correct.

 

Now just to humor me I still dont understand how to achieve the split approach.

 

Thanks so much for all your help though :) I have definitely achieved what I originally wanted: full parallel of the SimplifierX with independent FX for both channels from the HX FX.

Is there still a problem?

If you want to replicate the picture where stuff is routed to the Send 1/2 Output block: you can't replicate that when you use fx loop blocks because that would mean to use the sends twice.

 

The new posted patch seems correct, too.

No there is no problem! Its behaving as expected I just wanted to see what the split paths did with a send 1/2 and main l/r and how that differs. Thank you for all your help!
