Midi track key ranges for internal sound

Hello,
Key Ranges is great to layer sounds.
I'd like to use miditracks to split my keyboard and call sounds of other internal tracks.
I make a new midi track and send it to my plugin. The problem is that when I try to define a key range for my midi track it's always sending data to the whole keyrange of my plugin track.
If someone know the way to do that it would be great.
Thanks
Chris

The key range of a MIDI track doesn’t seem to affect the SendTo port, so maybe you also need to set a key range on the plugin track.

Thanks!
Yes, that's what I noticed too.
If I change the key range of the plugin, it works, but the point of using a MIDI track is to be able to control the same plugin with another MIDI track in another sequence on the whole keyboard or on another part of the keyboard. That should be possible but I can't find the way...
