SoundMan-Server can aggregate multiple sound cards in the same computer so that you can use many different (or the same) types of audio interfaces. For example you can put up to 6 MOTU PCI-e interfaces and/or and up to 9 RME MADI cards into a single computer for up to 576 outputs (and inputs). We have done both of these and more can probably be done but we haven't tested it beyond this.
We have a rack mount computer that can accommodate this number of cards and it is being used in the Brazilian National Opera and megachurches in the US. * Charlie Richmond - Richmond Sound Design - Skype: charlierichmond * http://www.RichmondSoundDesign.com <http://www.richmondsounddesign.com/> "Performance for the Long Run" * SoundMan-Server & AudioBox II - Virtual Sound System Core Audio Engine * LinkedIn & Twitter: charlierichmond<http://www.linkedin.com/in/charlierichmond> * Facebook: charlie.richmond * G+: https://plus.google.com/u/0/117175238910652375011/<https://plus.google.com/u/0/117175238910652375011/posts> * RSD on Google+: https://plus.google.com/101997019719186030659/ * Primary and much preferred method of communication is via skype On Wed, Mar 28, 2012 at 03:53, Dave Malham <dave.mal...@york.ac.uk> wrote: > Definitely agree, we use multiple Motu's a lot. and they do the job just > fine - tho the RME stuff is great as well. > > Just a note on synchronisation - we all use sigma-delta converters these > days and they, especially with the older designs, can have significant > latencies.
