I have a Behringer MX9000. I have an Alesis HD24. What is the best/easiest method of using all 24 tracks of the HD24? I have 16 tracks through the 8-bus and internal patching of the MX9000. Should I go Direct Out, Mix-B (which I am totally not understanding fully when it comes to the recording/playback routing side of things), or just use the Expander port and add a little mixer? Or what? WHAT???
