So if I understand correctly, my AES32 has the same matrix functionality as the HDSP cards, but the hdspmixer (and similar hdsptools) do not recognize the AES32. (Apparently hdspmixer hasn't been kept up to date for quite a while) Does hdspmixer just need the card definitions of the AES32 added or is the differences between it and the HDSP series more complex than that? Are there any patches floating around for this? -Reuben
