I notice that a lot of MIDI programs require jack-audio-connection-kit in order to emit sound. Do I need to somehow terminate pulseaudio before running jack, or will there be no problem with both on at the same time? Will jack-controlled applications respond to the volume slider of kmix, even though this is used by pulseaudio? And, when I am finished noodling, I will terminate jack, but do I need to somehow restart pulseaudio, or will it simply be working when jack stops?
