Dear Tascam Community, please help! I m newbie owner for Tascam DM 24, I using it in my studio for creating electronic instrumental music. I have a Lexicon MPX550 processor, and I want to plug it to Tascam via SPDIF 2 in and out. But my brain is blast! Please, I need step by step tutorial, how to setup routing (I dont have any expansion boards in my Tascam DM24). I m newbie, and I cannot understand this crazy routing matrix with digital sends, returns, and inserts!!! Thank You!
