Hi everyone!
I just got an organelle M recently and know a lil bit here and there about orac and how things flow. But, when I plug in my guitar and try to chain effects together nothing comes out of the output even though I can clearly see the input is working. I don’t know if it’s a bug or just an extremely easy fix I’m missing but any help is appreciated. Thank you!

Hi
There was a topic on this not long ago. The solution is described here:

> You have to go to the Parallel module (C#1 + encoder), then go to the Gain Chain you want to use by pressing F#2 for Gain Chain 1, A2 for Gain Chain 2 or roll the enconder to the right for Gain Chain 3 while you are still on Parallel and there you have to turn up the in gain from L and R
