ForumsSoftware ← multi-layered .wav files for Kaivo

How can I create those multi-layered .wav fils to load into the Kaivo Granulator? Didn't found anything in the manual nor in the internet.

Sorry, I sort of hid this information. It's in the readme: http://madronalabs.com/media/kaivo/_read_me_first.txt
I use Audacity (free) to make the files.
