Hey, I’ve been wondering is there any simple DIY module for stereo sound randomly smoothly switch between channels? Most of the modules are mono I guess, but effect to use one of the ambient sound to double it and for example delay one of the channels a little bit, smoothly go from one channel to another may increase a lot scene and ambient effect at all. As you can see I have no idea how to name it and search it myself : D I remember post-rock/ambient guitarists uses effects like this, maybe any guitar pedal? Here have some post rock to get the idea, had to be used on this CD.

it isn’t random but an output stereo mixer : > [@Which Final Output module?](https://lookmumnocomputer.discourse.group/t/which-final-output-module/193/5): > > This is 2 simple mixers stacked for 8 stereo channels with independent pots for left and right. Works great for me. Zero issues with plugging it into my Mbox 2. I would just add some CV in (maybe a simple vactrol) ---

Thanks, thats another module I have to choose - I think about some mixer with 2 stereo outputs - to listen live and to record one. But I guess thats another topic. Maybe look at it as a fader module? ---

if you add a CV input on the pots (right/left, not the volume pot), with a voltage sent for example by a Sample and Hold and an Env, you could switch the sound from right to left randomly ---

Yeah, but only with 2 states - on and off as I assume? I want something that could change the volume of the signals I guess? And then add as 2 channels to the mixer? ---

no with a CVin it’s not only on / off, with an Envelope Gen you can make a curve like you want. on this of @Doolang each input have his own panoramic pot (8 in total) ![CA45768A-B746-4846-8483-CB1D89D4DCCB](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/1X/0944c9e559761d77f209a060d5c5a1b79ebc2a93.jpeg) ---

Thanks. Seems to be more complicated that I though, will reconsider this option later : ) ---

You can use something like this if you were to combine it with a noise source and a sample-and-hold through a slew, I think: > **[CV Controlled Mono to Stereo Module-Eurorack Format](https://www.instructables.com/id/CV-Controlled-Mono-to-Stereo-Module-Eurorack-Forma/)** > > CV Controlled Mono to Stereo Module-Eurorack Format: The revolution in modular and semi-modular synths has produced a beautiful variety of new mono-synth options for electronic music and noise use, but one issue with mono-synths (and most Eurorack...
