Re: NO benefits from using ASIO ? Reply #50 – 2019-01-24 08:28:19 I personally use ASIO with foobar because of the custom channel mappings. My audio interface has 4 outputs, and my setup involves my studio monitors on the main outs (1/2), and a sub on 3/4. With the custom channel mappings, I can set outputs 1/2 to front L/R and then outputs 3/4 to LFE. I use this alongside the subwoofer DSP as a linear phase crossover with adjustable delay for matching phase.
