That's a great observation!
I will ask around.

So we call it "Touch sensitive motorized faders".

Ahhh, good call. I'd never really thought about what that meant back when I first bought this.

Do we know if it's actually used anywhere in the firmware?

Please describe the steps you used to monitor this activity. Thanks!

Any kind of MIDI monitor will work. In particular, I used MIDI-OX http://www.midiox.com/ which runs just fine on Windows 10.

Be sure to enable MIDI for your console. https://pae-web.presonusmusic.com/downloads/products/pdf/StudioLive_Series_III_Mackie_Control_Emulation_DAW_Control_Addendum_EN_25032019.pdf

In MIDI-OX go to Options -> MIDI Devices and select your console's ports.

Note that by default this program will create a loopback between the input and output ports. This is a good thing because both the Mackie and HUI protocols*/modes rely on the feedback from the program to "acknowledge" a change. If you don't have the feedback loop enabled every single action you take on the console will be undone about a second later.

After that you can start moving stuff on the console and you should see it show up in the Input window of MIDI-OX.

Additional note: depending on the program you want to use this with you may need to keep the feedback loop in place via MIDI-OX even while you're using your program if you don't want faders to keep moving back. I use my console with vMix but since vMix isn't compatible with the Mackie or HUI protocol* it doesn't know it needs to send feedback. As such, I rely on MIDI-OX's feedback loop to do that for me.

* I realize this isn't really a protocol since it's just MIDI but each mode is expecting certain behavior.

I just stumbled across this: https://youtu.be/46gsG96sYvI?t=255

So yes, the touch sensitivity is used in the the firmware. In particular in DAW mode.

The Owners Manual doesn't really explain what "touch-sensitive motorized faders" are, but it mentions it in section 4.1. The StudioLive consoles do use this feature. You can not just move a fader. You have to first touch, wait 0.68 or so seconds and then move the fader. Studio One and DAW Mode also uses touch sensivity as indicator of what fader is in use (e.g. for sends or cue mixes).

Your response is specific to MCU/HUI modes. Sorry, I assummed your original question was referring to monitoring MIDI activity while in DAW Mode for Studio One.
