Bc2000 (for the BCF2000 & BCR2000)

Hi, I'm new to this group, a user from the kawai k3 group forwarded this group to me because I asked if it was possible to use a bcn44 with a kawai k3 (which uses sysex messages). From what I've gathered you can use a BC2000 with the K3, but the learn function on the bcn44 doesn't work with sysex. I was overjoyed when I found a bcn44 editor from Mountain Utilities on this group, however I'm confused with how to use it. It says on thier website "contains support for 'custom' MIDI messages (up to 11 bytes), in particular System Exclusive messages" so I'm hoping I can use it to control filter and lfo parameters on my K3 synthesizer. The program came with no manual, and I'm confused about how to use it, if anyone has any tips, please let me know!
Thanks!

p.s. some users from the k3 group decoded the sysex messages but I don't know how to input them into the editor...
