attached my patch.. requires [spigot~] ( http://ydegoyon.free.fr/software.html )
basic instructions:
'very slow' or 'never'
*open pd, and this patch*
use the w,e,y,u,i,o keys for effects on track 1 use the s,d,h,j,k,l keys for effects on track 2
let me know if it works for you or if you have any problems
**if you are on linux, or osX, use the [playlist] external instead of openpanel - much easier to load loops this way**
