[linux-audio-dev] More sequencer engine questions

Found some good reading material on real time programming and now have a couple more questions if anyone can share: - what are the pros and cons for a sequencer engine of using pthreads in one address space vs seperate processes spawned by one application? Anyone know what the various linux real time sequencers use? - if I do POSIX pthreads or multiple processes, will the code be an easy port to MacOSX? And what about windows, would one be able to run it under Cygwin or something? - if I embed another audio app within the project ( looking at embedding Csound with the Csound API ) is this going to make it much more difficult to sort out priorities given that Csound kinda has to be allowed to keep running. I figure it would be second highest priority after the engine Thanks, Iain
