Hi All, Basically what i'm after is to be able to record 3x wet signals at the same time via a suitable audio interface into my DAW. Set up consists of a pod hd 500, Yamaha digital piano & electric drum kit. The main issue i've encounted while searching for a suitable interface is the lack of line inputs. I was looking at the Focusrite 6i6 as it's in my price range, but I was unsure how i'd connect all 3 instruments? I'd planned on running the pod hd500 in to the interface via the XLR Out on the pod to the line input of the audio interface (via XLR to TRS 1/4) here is the problem... the research I've done also recommends connecting the digital piano via the same set up (R ----- L\+R out to audio interface line input) & i'd like to run the same type of connection to the electric kit... Is this as simple as me having to fork out the extra cash for a higher end audio interface, or can I run these 3 instruments via a different set up into the audio interface? I'd even be happy being able to record 2 wet signals at once. Any assistance would be appreciated. Thanks :)
