[LAU] State of RME Raydat?

Hello all. I'm new to the list, although I shouldn't be. I've been running a Linux-based recording studio now for 10 years, and doing it professionally for 3. I use ardour, hydrogen, muse2, mixbus, LinuxDSP, and a bunch of OSS LADSPA and LV2 plugins. I recently decided to jump into the RME arena (currently using an Echo Audiofire12 for my converters and interface, and it works beautifully) and am finding it oddly difficult to get good results from google concerning the state of new-ish RME products and Linux compatibility. Has anyone out there used the Raydat interface successfully with the WCM (word clock module) add-on card? Does the hdspmixer work with the raydat? Are there any shortcomings, or any reason I shouldn't use it in a professional studio? I thought it'd be a good idea to refresh the internet new RME info, because the latest update I can find is from September of 2011. Any info is welcome! Thank you! --Jason www.advancedbudgetstudios.com
