How to create a footswitch block to switch between 2 inputs on one preset

[DOndek]

Hi all, I have a couple patches where I use 2 inputs (ie Return 1 and Return 2, or Guitar In and Return 3) in order to accommodate 2 input signals from the same guitar which have their own signal paths in the preset.  I'd like to have assign a footswitch that is essentially an A/B switch that allows me to switch between the 2 input sources (and therefore switching between the 2 respective signal paths in the preset).  What's the best way to do this?  Thanks!

If I understand correctly, you have ONE guitar and TWO signal paths for it and want to switch signal paths?

Split your paths immediately after the Guitar In. Change the Split Block to A/B and assign a FS to it.

It will now toggle the signal between the paths.

Then rejoin the main path at the very end before the Output Block.

Hi,

 

Follow the information given in the post above from @rd2rk which will provide you with the necessary switching option.

 

Judging from your original comment, regarding Return 3, it seems to indicate that you’re using a Helix floor, or Rack unit. If that’s the case you can also use the same technique as mentioned above, but rather than a foot switch you can assign your EXP to smoothly bend, back and forth, between the 2 separate audio paths. Whichever you find easiest for your situation.

Here’s a video:-

 

Hope this helps/makes sense.

Hi.  Thanks for the replies @rd2rk and @datacommando.  I did watch that video before I posted this and did some searching, but I don't think that's the solution, and it's most likely because perhaps I didn't explain it well enough.  I don't need an A/B to split the I have several guitars/scenarios where I need to create presets for this type of situation, but will explain one of them below.  Hopefully this additional detail helps:

 

I am running a Helix Floor.  I have a Warmoth guitar that has mag pickups for the electric and a Fishman Powerbridge for the acoustic, therefore 2 distinct outputs from the guitar for which I have a preset that has 2 signal paths.  The mags Input into Guitar In and the piezo Inputs into Return 1 on the Helix.  What I'd like is for a footswitch on the Helix which acts as an A/B between the 2 signal paths, so that when it's not engaged, the mags path is live (and the piezo muted) and vice versa.  

 

I hope that makes more sense.

To clarify: those two signal paths are completely separate? 

You can toggle paths using Controller Assign on fitting level parameters in each path with the same footswitch. I.e. a level parameter in path A is on (0 dB) while another in path B is off (-60 or -120 dB).

Or you put a Gain block in each path set at -120 dB and Bypass Assign them to the same footswitch. One gain block is bypassed while the other is active.

Hi @Schmalle, Not sure I follow the 'level parameter' suggestion, but I 'think' I follow what you're saying on the Gain block suggestion.  I think I should have included one of the types of presets I'm currently using so that people can visualize it better (attached to this reply).  Thx!

Attached version should work.

You needed a FS, so I used the Piezo Tuner (FS5). Just put the tuner before Return1 instead of in the Loop.

 

FS5 now modifies the LEVELS of the 2A and 2B Output Blocks, cutting out the Piezo when ON and cutting out the Guitar when OFF.

Thanks for sending.  I imported it and tested it out.  It works, except that the FX Loop I have in the chain is for an external tuner and another pedal to enhance the piezo path, so I need to figure out how to get that to work.  

 

Just so I understand what you did, looks like instead of a new block you altered the db level at the end of the first part of the output path for each path and then assigned that to FS5?  

 

While you were creating that, I tried the other suggested approach of adding a Gain block at the beginning of each path and assigning them to FS2 (which I had to lose one of the existing footswitch effects to do so (attached).  With your way, it looks like I don't have to add 2 new blocks which is good but I need to figure out the FX Loop situation.  Thx!

Here's the same functionality using Snapshots instead of a FS.
