I have 6 mics plugged into my FireStudio Project audio interface. I like the zero-latency monitoring available by plugging headphones into the interface, but I can't add simple effects, like reverb. If I want to hear effects while monitoring, I have to plug the headphones into my computer. Is there a way to apply effects directly on the FireStudio, so I can still use its outputs for monitoring? I read a little about sends and returns, which (i think) route the audio through an effects device, but is there a way to do this without additional hardware? What's the actual term for applying effects directly on an audio interface?
