• ### Dry/Wet mix parameter for effect pedal

Hi, I am working on my final project for my course and I have been using Pure Data to program an effect pedal. Sorry, I am new to programming and I have been struggling quite a lot with it and I was wondering if anybody could give me a help with a problem that got me stuck.

I was wondering how to make the Dry/Wet parameter for the effects without having one on top of each other having an increase in the gain as a result.
I would need to figure out how to even out the signal as the wet signal gets increased in the mix.
What I mean is I would like to know how to make an inversely proportional reaction between the dry and wet signal so the more one decides to increase the wet signal, the more the dry signal decreases depending on the amount of the other and viceversa.

There are a already a couple of threads in the forum talking about this, but no one really managed to give a simple/practical/straight-forward answer to this, with a result of trying all the suggestions found already and not being successful with it.

Sorry if it sounds a bit tricky by words, but it is a simple concept that I cannot figure out how to make in practice with Pure Data.

Thank you guys

• @Luke :
Simple enough.
Use a value that ranges between 0 and 1 for the wet portion. Subtract that from 1 for the dry portion. Multiply the wet signal by the number for the wet portion, multiply the dry signal by the dry portion.
When you set the wet portion to zero, then the dry portion will be 1. When the wet portion is 1 then the dry portion is 0.
Have a look at the attached file to see what I mean.

• @JosephEoff Yes, that looks definitely like it! Awesome. Thank you very much!

• @Luke Hi
If you did need 100% of both signals, or for instance an echo with 100% dry + 20% wet, you can use [moses].
