i hope someone can help me, i have a yamaha kx8 midi keyboard that came with cubase ai4, i have a tascam us144 audio interface, a behringer 2024 dsp effects processor, and a crate 8 channel mixer. How do i connect all the units to run my guitars and mics thru the mixer thru the processor and still controll the sounds of the software thru the keyboard and be able to record. i hope i typed all this correctly any help will be really appreciated. thanks
