I have a question about connecting 3 different digital devices together via wordclock bnc connectors.

I am connecting a digital mixer, an Echo Layla, and an PreSonus DigiMax mic preamp. I want to use the PreSonus as the "master", and then slave the Layla and the mixer to the Digimax. All 3 of these devices have both workclock ins and outs.

Just interested in how people have delt with their rcas on the delta 1010lt. Looking for options and suggestions. I am going to need to hook-up about 8 mics and cant figure out how.
Thx

Hi! Can somebody please shed a a lot of light on how to proberly midi up my MPC and Roland MC307. What i am tryin' to do is play the keys on the 307 and have them record into the sequence of my MPC. I've recently learned that i needed a mixer to do this (duh) and was successful at doing it with my friends Triton.

I'm curious to know how many people connect the direct outs of their desks to the multitrack ins and how many connect the desk bus outputs? Does anyone use a combination of both?
