one way is to use tot , an external that gives you tcl access in your patch, for the usual file manipulation functions, search for "folderglider" for an example of this. if youre on os x, the shell external would proably work to, to just spawn an ls and grab the results. Zexy external would proably be helpful for dealing with the resulting lists/symbol strings...

look at the bonk~ help file.. for finding the beats anywyas, perhaps setting a high threshold and trying to get one hit per measure (depends on how its mixed). perhaps finding 4 or 8 hits then dividing...of course this technique is a lot easier if its house music than jazz drumming/

search for 'flashserver' . havent tried myself..

good luck~!
