[LAU] freecycle, its alternative and beat detection

[Robin Paulson]

hi all,
i've got a situation to solve, and i'd appreciate some assistance from
you folks if possible. i have several pieces of audio i have recorded,
which consist of a series of 'percussive' sounds (i enclose that word
in quotes, as the noises are not made with a drum kit or similar, but
bear a resemblance to the sounds from drums).

now, i would like to extract the rhythm from the audio samples, and
use it as a rhythm to trigger other audio samples.

i have tried doing this with freecycle, but there are some issues with
it - it detects the sounds wonderfully, but exporting a midi file
fails, it creates a 73 byte file only. however, it does export .akp
files fine. i tried it on ubuntu natty and oneiric and got the same
results on each.

freecycle appears to be unsupported, it doesn't look like it's changed
from version 0.6.1.1alpha in a few years, and has since been excluded
from ubuntu and debian.

i also tried ardour v2.8, which worked very well, but doesn't export
midi in any way which is useful

so, are there any alternatives here? will i need to build something in
pure data, or are there any decent plugins for doing this, either in
realtime or offline? are there any floss packages useful to me which
understand the akai (.akp) format?

cheers,
