Hey hey. I've recently been working on revising the Illustrated OMT booklet PDF linked in my signature, long over due for an update. Still working on addendum stuff: introduction & overview, channel assignments & file management, mixing, playback options, technical discussions, a brief history of OMT development, potential advanced arrangements, table of contents..
However, I think I have the setup section with diagrams of OMT3 through OMT8 setups pretty much nailed down. Attaching those here, pre-release, potentially still subject to final edits. May roll most of these and a few others into a single document and replace the outdated version in my signature prior to getting everything completed.
