How can I route 4 incoming audio streams to stereo? (-Via a simple plugin?)

[GhostsonAcid]

Hey,

Does anyone have a plugin or method to achieve this?
I’m exploring route Pin Connections more, and holy shit it’s awesome (…but certainly bewildering).

I want to ‘collapse’ 4 audio streams into 2 (-back into plain stereo), as indicated here with yellow lines:

…
However, I currently assume what I actually need is a plugin that has 4 input pins and 2 output pins specifically, as poorly shown here:

So, does anyone have a simple LV2 or Lua DSP script that does this?
If not, then I can probably just make one.

Also, if there’s another way for doing this, then please let me know!

Cheers,

Take a look at the LSP mixer family; they seem to be quite flexible. This one, for example, looks like it can do the trick:

Hi,
I am not expert in this area, but it seems that musing around with « pin connection », it would be possible to reach your goal.
By inserting a track and send output 1 and 2 on input 1 and output 2 and 4 in input 2 of the track, it should make the trick.
Maybe you will have to make a real time « bounce » of the audio. Meaning: press « record » and let the audio be printed on the aux track?
Just how I would get out of it on my side.

Correct.

One way is to add ACE Cross Fade (comes with Ardour) and set the x-fade to the center (A/B = 0.5).
