Now that you told it, I gave myself a shot of it. Mmmmmm...! Simple and
fast and feels so good.
However... I'm afraid of locking myself in pd-l2ork. That would mean that
my songs are basically in l2ork.
Where does this thing store its data? Is it possible to dump it out in raw
On the other hand, you've been using l2ork for a while, right? Can I ask
you "how does it feel", do you feel locked in, etc? You no miss 0.43
