"The simple appearance of Olivier Guilyardi's Jackbeat (Figure
3) might deceive you. It seems to be a small-scale rhythm
programmer, when, in fact, it's a powerful pattern sequencer. As
its name implies, the program relies on JACK for its audio engine,
but it also supports PortAudio, ALSA and CoreAudio (on OS X). Using
Jackbeat is essentially the same as using a typical software drum
machine, with the added attaction of full JACK transport
capability. Thanks to that feature, Jackbeat can be used either as
a standalone virtual rhythm box, or it can be integrated into a
complex environment of other JACK-savvy and/or OSC-aware
"Jackbeat requires a contemporary Linux distribution to meet its
dependencies, but most modern systems should compile the program
without complaint. However, if you've replaced JACK with your own
build, be aware that Jackbeat's build process may fail at the
linking stage with an error message about a missing libjack.la.
Apparently, the waf build manager doesn't install (or even build?)
the static components needed by the public Jackbeat source package.
I'm happy to report that Olivier Guilyardi has fixed the problem in
the latest SVN code, and I was able to compile and install Jackbeat
0.7.1 on my 64 Studio 3 beta box."
