[LAU] freecycle, its alternative and beat detection

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, -- robin http://fu.ac.nz - Auckland's Free University
