I guess I should explain that I don't have an external soundboard. I'm just running everything through my audio interface. So i'm trying to figure out how to set it up in my DAW so that i can get a bus that sends to my sampler. There should be a way to do it cos Panda Bear used the reverb from his SP 303 sampler for his album Person Pitch and I highly doubt he recorded the vocals wet, given sound quality of the final product. Dunno if there's any point in posting this, but this is an example of his stuff featuring the reverb. Panda Bear - Carrots - YouTube
Another reason I'd like to figure out how to do this is because I'd love to use my effect pedals for my guitar without recording wet. I want to be able to record everything dry so I have complete control when in the mixing phase.
