It's pretty<br> exhaustive in the case of jack_delay's man page I'll admit (though the<br> need to differentiate between JACK1 and JACK2 and various behaviors is<br> really good for a head ache, requiring more of 2. than users might have<br> readily available, probably hard for an insider to the program to<br> fathom).<br> <br> On the LilyPond (batch music typesetter with plain text input language)<br> user list I often get puzzled at requests of the "can I do this" kind of<br> questions where one wants to shout "why don't you ask LilyPond?". Some<br> people seem more comfortable risking annoying another human rather than<br> annoying a program.<br> <br> At least with regard to latencies it is rather tricky to "just try".<br> <br> -- <br> David Kastrup<br> _______________________________________________<br> Jack-Devel mailing list<br> Jack-Devel@lists.jackaudio.org<br> <a href="http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org">http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org</a><br> </div> </span></font></div> </body> </html>
