Personally I am less interested in chaining fx chains together and more interested in having multiple fx chains output to the same ports (i.e. mixed together). Suppose I have optical output 1 and 2 connected to a pair of speakers for monitoring, then inputs 1-3 of different instruments 1 – guitar 2 – bass 3 – vocals I could be using my guitar FX chain which takes 1, adds effects, then outputs to 1 and 2, then I could drag and drop my vocals FX chain which takes 3, adds effects, then outputs to 1 and 2 as well. As it stands, I find myself needing to make Session X, Session X + Vocals, Session X + bass, Session Y, Session Y + Vocals, etc. so that I can have everything in one FX chain. I wouldn’t mind doing this with an external mixer, but I haven’t been able to find anything that can work with digital signals (take the H9000 digital outputs and mix into a 2 channel optical or coax).
I just saw that this was posted today, but it seems to be an old thread.
Depending on the algorithm requirement, if you can get all the FX in 1 chain, then you can just mix to 1 set of outputs by wiring the parallel FX outputs to a single set of outputs, though you will have limited ability to mix.
If you want a dedicated mixing algorithm, I have a free one and a paid premium one available at https://godlike.com.au/index.php?id=420 that can mix 8 outputs (or 2 stereo pairs) down to a single stereo pair.
