It appears to have been more than a year since the company was mentioned at all. Has anyone ever tried contacting them about specs to write drivers for newer devices than the ones listed on their developer page? http://developers.marian.de/ Specifically, say the Trace D4 cards? It looks like the newer cards like the Trace D4 use a FPGA for everything rather than some sort of programable logic attached to a PLX PCI interface chip, which I'm guessing means that their legacy documentation bears little relevence to their current cards. They do invite people to contact them about information not found there. One appealing aspect of their products is they allow hardware syncing of different cards (which M-Audio also does), and they have a wide variety of card types (all analog, all digital AES, ADAT, with or without midi, etc). -- Joshua D.
