JLCooper Eclipse Ethernet 2.6 for OSX - Manual (Page 63)

You may notice that there are more controls pictured in this window than actually appear
on the Eclipse MX hardware. The little button above each fader represents that fader’s
touch sensor, which is treated like a separate control.
The Faders can be assigned Native and Custom MIDI Actions, Developer and Raw
Ethernet Actions, and Fader Emulation Actions. For Emulation Actions, you can assign a
channel.
