How to set up a reverb insert pedal on two channels”

I would like to insert a reverb pedal (via Insert Send/Return 1+2) on two sources at the same time:

Hello everyone, thanks for your help.
I would like to insert a reverb pedal (via Insert Send/Return 1+2) on two sources at the same time:

Input 1: my piezo (cello)

Input 2: a Schoeps microphone

Each signal goes through separate processing (EQ, compression…), then I want to merge the two and send them together to the same Insert (Send/Return 1+2). But I’m struggling to achieve this.

The only solution I found is:

  • Line 1: piezo → volume block → comp → EQ → multi out
  • Line 2: Schoeps → comp → EQ → delay → multi out
  • Line 3 = Lines 1 and 2 mixed → insert

This works. But the problem is as follows:

I have 2 scenes, E and F. Scene E is normal, and Scene F mutes the volume block, which allows me to only have Line 2. However, since Line 3 is a mix of 1 and 2, and I cannot mute Line 1 separately because they’re mixed in that line, this mixing solution does not work properly.

Is there a simpler solution?

Thank you very much for your help!
