Hi,
a few years ago I made a drum machine with scrubbing, and showed it to
some people at the LAD booth at LinuxTag 2003.
Recently (at linux.conf.au 2006) I realized I've sat on the code and not
released it.
This is not a "release", but a challenge; here's some code, and some
instructions for building it:
http://trac.metadecks.org/wiki/BeatfishInstall
Beatfish is built on libremix (which is also not-quite-released; I'd
like to freeze the API sometime this year though ;-) and Evas (a very
high performance graphics canvas built for Enlightenment 17). The plan
is to make a way of developing cute music machines, using DSSI and all
that's good. For now, beatfish is a pretty basic Jack toy.
enjoy :)
Conrad.
