Looking for a pedal to switch input 1-2

hi guys!! i’m looking a pedal to use with my chapman stick, that have a stereo inputs into mod duo, that invert the two input to send the input 1 into the chain pedals built for input 2 and reverse for input 2 to chain pedal of input 1.
That’s help me much to have more sound possibilities and reduce CPU pain.
Thank’s at all for your precious help


If I understand you correctly, you want to have your chapman stick (which has 2 outputs, if I’m not mistaken) connected to your duo such that chapman_out_1 → duo_in_1 and chapman_out_2 → duo_in_2.

Then, inside the Duo, you want to send duo_in_1 to both duo_out_1 and duo_out_2 through each of fx_chain_1 and fx_chain_2. And also send duo_in_2 to both duo_out_1 and duo_out_2 through each of fx_chain_1 and fx_chain_2.

If that’s correct, you can achieve this by using multiple connections like in the attached image:

you’ll probably want to add some 2:1 mixers to get the right blend of both channels, but this is the basic idea (assuming I understand what you’re trying to achieve)


I was just thinking through this again and you probably don’t need the double connections on both ends, just one or the other. Unless you want to do some interesting mixing.

If I understand you correctly, you’re trying to sometimes do:

Pickup A → signal chain 1
Pickup B → signal chain 2

But also press a button and switch that to:

Pickup A → signal chain 2
Pickup B → signal chain 1

If that’s correct, you can rout each input into a separate instance of a toggle switch that flips the signal between one signal chain or the other signal chain, and use CV Parameter Modulation to map both toggles to a single foot switch or midi switch to flip both toggles simultaneously.


your explanation sounds better :slight_smile:


Now that I think about it–without my Dwarf in front of me, and with the plugins site still down–I think there’s a fully stereo toggle switch available that’s 2-in and 4-out, but it’s not necessarily pre-loaded on the device. That would let you do this with a single plugin and not have to map to the CV Parameter Modulation plugin.


Might be one in the Beta store if at all–see these threads:


Okay—I don’t mean to keep dominating this thread, so my apologies for that—I checked my Dwarf and the 2-in 4-out does exist (Switchbox 2-1 ST) and is installed on my device, but it won’t actually work for the purpose—because it diverts rather than swapping, which I should have of course realized in my head.

So, I stand by my first post as the best solution.

HOWEVER—if you don’t necessarily need the swap to be instantaneous, you could mess around with Stereo X-Fade to see if that works as a single plug-in solution. I haven’t experimented with it so I don’t know how short you can set the fade to, but on the other hand a long slow swap between pickups while you’re playing could be a really interesting take on a filter effect depending on how you EQ.

EDIT: I’m an idiot. The one that won’t work is Switchbox 1-2 ST, which is 2-in 4-out, so that was correct. But I didn’t mention that one above. On the other hand, Switchbox 2-1 ST which I did mention and is 4-in 2-out will work:

Sorry about that brain fart—been dealing with a lot of elder care lately, my mind is a bit scrambled.


I can relate to the brain fart :laughing: To the OP @Gabry_Stick if you want to experiment with serial and parallel switching, I have a post about that, too. I’m a little jealous, as I wanted a Chapman stick when I was younger, but had no way of acquiring one when and where I lived :slight_smile:


yes! and if it is possible also bolt pick up A+B → chain 1 or pick up A+B → chain 2


Genius!!! love you!!! thanksss


i can’t found this pedal on my library causa a can’t log to Mod Cloud, can you share me the pedal???
thank you

I’m not sure when I’ll have a chance to get you that switchbox—I don’t have a lot of time to dive into the file system on account of the aforementioned elder care situation. I’d say hang on tight for a little bit to see if the Company Formerly Known As MOD manages to bring the plug-in store back online; if it doesn’t then obviously all of us will be playing trading cards. Unless somebody already uploaded it here? Anyone?


thank you for your help… is a embarrassing stalemate situation, i hope the company resolve soon… and if you or anyone can share me the plug in I will be very grateful to you.


Again, you could use the original solution in the meantime—both CV Parameter Modulation and the mono switch should be pre-loaded on your device. A little more setup but not much more CPU intensity. I use it all the time which is why it was my first thought.
