Trackrat and all others who have responded...Thank you for your input.....
Trackrat, So what you are saying, is that I could use a seperate mixer and route the outputs of that mixer into track 1 of my 4-track? That way I could mix the drums on 2 seperate channels and then route it into 1 track. But essentially, isnt that the same thing I am trying to accomplsh with a splitter (without the expense of buying a seperate mixer)? As you mentioned, by using a splitter, I wont be able to mix the channels independently. How much more of a difference will it make if I use a seperate mixer?
