No Trick For Series Loops w/ LS-2 Right?

[jufros]

What I want to do is put pedal series 1 in loop 1 of an LS-2 and a second LS-2 in loop 2 of the first LS-2. The problem with this is, I don't have anyway of going Loop 1->Loop 2 while still retaining the ability to blend Loop 1 and 2 in parallel. Is there some kind of a workaround that I'm not thinking of here or do I need a different type of line selector altogether.

I think you need to draw us a picture!

Fundamentally, if I have three loops A, B, and C, I need to be able to run them A->B or A->C or B->C or A->B->C in series and I need to run A+B or A+C or B+C in parallel. What's the best way to do that?

No workaround.
An accointance of mine started working on it, reverse engineered the pedal and drew all the plans to add a series/parallel switch but never finished the project.

Can you do it with 2 LS-2's and a 2 channel series bypass strip?

Also, what happens if you have something plugged into the receive jack of one of the LS-2 loops but nothing in the send jack for the same channel?

I know that I can definitely do two sets of pedals in series or parallel with two LS-2's, and two of them is more cost effective and versatile than one X-Blender. They'd take up the same amount of total board real estate but I need one on each board.

Whatever is plugged at the receive will come out and you can adjust level with the corresponding knob.
Doing this you can use the LS-2 as a 2 channel mini-mixer.

With the exception of A+B in parallel (but with the addition of B->A in series) I am close to finishing a buffered routing box that will do this. It also has adjustable gain compensation and low frequency pass-around for each loop. I am a ways off finishing the prototype and I'm not sure if I am prepared to commercialise it just yet.

Maybe I'll find the motivation if people knock down my virtual door with incredibly generous offers!

No. With that setup you can achieve a really arse-backwards way of soloing one of the channels, which I had to do once, but you can't set them up in series.

Edit: Sorry - didn't see your specification of 2 LS-2s. I think you could get an equivalent solution with a bespoke build for less money.

I think I figured out a solution to my problem that I can definitely live with.

We have two LS-2's, which we'll call LS#1 and LS#2.

The meta signal chain is:
MXR BOD->LS#1 Input->LS#1 Output->LS#2 Input->LS#2 Output->CE-5, Source Audio Tri-Mod Phaser->Duncan Shape Shifter

LS#1, Loop 1 (L1.1):
L1.1 Send->GI Fuzz->BlowTorch->FX25->AF-9->BMS->L2.1 Return->L2.1 Send->L1.1 Return

LS#1, Loop 2 (L1.2):
L1.2 Send->L2.1 Return->L2.1 Send->L1.2 Return

LS#2, Loop 1 (L2.1):
L2.1 Send->L1.2 Return->L1.2 Send->L2.1 Return

LS#2, Loop 2 (L2.2):
L2.2 Send->Orbit->Heliotrope->Brown Dog->Enigma->Moog->L2.2 Return

If I use LS#1 in output select mode and choose output A, then L2.1 becomes identical to L1.1.
If I then put LS#2 in A/B mix mode, I have both loops mixed in parallel.
If instead I put LS#2 in A/B/Bypass mode, I have either 1.1 (since 2.1=1.1 right now), 2.2, or just the BOD soloed going to modulation.

If I put LS#1 in A mode and LS#2 in B mode, then I have 1.1->2.2, which is both loops in series. The series loops are then sent to modulation.

I think this is a pretty elegant solution if I may say so myself.

A double LS-2 combo is basically an X-Blender, but I like the fact that I can have one LS-2 on each board.

At this point I either own everything I need for this setup or have it coming to me in the mail with the exception of the Brown Dog (definitely going to buy) and the Heliotrope (still on the fence, might be redundant with the Orbit)

Agreed. I had to make an Excel spreadsheet and stare at it for a bit to figure the whole thing out.

It fundamentally makes sense though. If you have two pedals (two LS-2's) in series, then you can run them in series. If you have something in the loop of an LS-2 (one of the other LS-2 loops), then you can run it in parallel with the second loop of the first LS-2.

Actually, an X-Blender is half a LS-2.
