Re: Running jackd.
Hello,
Jack is a low-latency audio-server. It is the defacto standard for
professional audio software on Linux because it is easy to program and
allows to route audio streams between applications in real-time. Most
sequencers and most other music related software only support jack for
audio i/o because jack also talks to the hardware. See www.jackaudio.org
So you have two options: Either installing jackd and qjackcntrl as a
gui frontend. Or disabling audio support in your sequencers. Many
sequencers like rosegarden or muse can use alsa midi if audio isn't
needed. However this might change anytime in the future as jack can
also handle midi connections.
