You're actually going to want 6 RME9652's if you want 72 channels at 96. In jackd/engine.c, change engine->port_max to 512. I think you won't need all of those, I think you'll need 304.
You can slave them together using pcm_multi as long as they're all linked with a master clock, alsa won't do it for you. Look for pcm.rme9652_96 in the archives, and if it's not there, I'll send it again. Be sure to use recent alsa, because syncing multiple cards kicked off a code change that prevented lockups. I'd be interested to know how low you could set your latency before jack kicks something out. _J In the new year, Patrick Shirkey wrote: > I have forwarded this to alsa-devel as there is probably more luck > finding the answer here and it would be a valuable thread to have as a > resource. > > R Parker wrote: > > Hi, > > > > I can't help you much, however, unless JACK has > > recently been worked on I think there's a 32 track > > limitation.
