gacki,
yes, I think you're right. Maybe working with SysEx the Midi Channel must be there too? I think I read it somewhere.
I found the post I was referring to in my first post, it's by fader8.
"For NRPN controls, create a fader object in the Environment. Set the output parameter for Sysex and an event list type window will open. Create 2 controller events here. Define the first for the NRPN number of the synth parameter you want the fader to edit, the second for controlling number. Make sure the second controlling message is highlighted before you close the window because that's what tells Logic which message will be changed when you move the fader. "
