[Jack-Devel] Multiple latency across jack

Is it possible to have different signal sources handled differently by jack ? As an example, Mixbus uses jack directly and runs at 44100 buffer 128/2 I have other applications running under emulator that needs deeper buffers and longer latency is not an issue. These other applications all use pulseaudio and I dont know if pulseaudio causes the overruns and resultant rickety sound. I am really not familiar how pulseaudio works with jack. At the moment both pulseaudio and mixbus/jack outputs sound simultaneously to the same output device without problem At the moment I cannot find a way to increase the latency for all other sources than Mixbus. The other sources needs larger buffers not to work intermittently as it is now seemingly forced to use the same buffer size as mixbus which works flawless at 128. How should I go about it to run different sources at different buffer settings ? This is a bit above what I could find online in the Faq. Or should I find a way to send all these applications directly to jack for better buffer handling and somehow cut out pulseaudio ??
