I recently bought a bunch of things for my recording studio including, an antares avp-1, Focus rite ISA one, and an ART VLA II tube compressor. I have a 48 point patch bay in which I have the aux sends and returns from my alesis multimix16 as well as the outs and ins from all above said unit connected to. I can patch them so that my sends are running through them, but it does not run the signal back to my track that i want affected. The units all show that the signal is going through them, with the exception of the focus rite preamp, but the final signal is not affected. Can I not do this? Do they need to be plugged into an insert jack? If so, my mixer does not have any and is there any other way to set this up? Sorry if my post is confusing, but I am relatively new to using multiple signal processors.
