Sorry, I’m not sure what you mean here.Every factory algorithm supports 2 in / 2 out at the minimum. The only algorithms on my H9000 that have less than 2 in / 2 out are custom algorithms made with RNBO.
You could accomplish a 4 algorithm FX Chain for your left signal and a 4 algorithm FX Chain for your right signal by using 2 mono inserts or effects sends with a DAW or mixing console.
Additionally, any algorithm can be fully panned left or right using the algorithms general settings.
