Hi there, A colleague of mine is having major problems using multiple (three) RME Hammerfall cards using Mac OS 9 and X and consulted me for help. The problem is that he has to transfer a few hours of 72-channel music (recorded with Mackie HDR's) to his harddisk for further mixing and processing. I only have experience with (single and dual) stereo cards using alsa, jack, ardour and ladspa. I wonder if anybody have experience with multiple RME cards using alsa, and particullary experience doing such a task with mentioned tools? I haven't had the chance to examine his (Mac-related) problem but it sounds like he might suffering from problems related to his power-supply? Regards, Ronald van Engelen
