I don't really understand. Guitar Lab seems like the thing to use to edit the B3N, but here's the forum with patches for Tonelib. I don't really get how they are related - did Zoom used to use Tonelib and now they use Guitar Lab? Can these patches be used via Guitar Lab? If not, how do you use these with Tonelib? When I try to open these .zb3n files in Guitar Lab - it never comes up in the Patch Pool. Thank you for any help.
