There shouldn't be an issue with MIDI value ranges. You can check out this link on midi2lightroom.com for a detailed explanation. The gist is that the interface controls the settings based on the type of "function" being mapped. Control settings/values are user-definable so can map to -M to +M as needed. The software interface also sets the controller's value/knob when switching between photos, ie. syncing knob's value auto-magically to match the photo's current values.
 
I'm using LR + Behringer mini-touch ($69) + midi2lr. It's a great little combo. And, yes, I'm still dreaming of the day when AP supports a midi-interface.

I wasn't sure where to post this idea, but here goes...

I just saw this today. An open source app (midi2lr) that lets you control LR via a midi controller. The obvious benefits are that you can have a hardware or virtual (think IPad based) device with dedicated analog controls (sliders, buttons, toggles, etc.) custom tailored to interact with AP.
 
Take a look here to see what I mean.

What a great interface for interacting with a photo editor!
 
There seems to be 3 components needed:
1. AP API (possibly via the Extension specification?)
2. MIDI2LR (fork open source project to create MIDI2AP)
3. Midi controller. These range in price from $ - $$$.
 
Is their a high-level API for AP to allow for this type of input? Maybe via an Extension? Not sure as I haven't been able to find any documentation around this specification.
 
Here is another example showing LR being controlled with an inexpensive midi controller.

Thanks for your time.

I haven't seen this before, so I figured I would share. This is a simple cartoon like effect. This is similar to the pseudo cell shading tutorial by Affinity, but that's because they used the edge detect tool too. So for what it's worth here we go.
First copy your background layer, CMD-J
Go to Filter, Detect, Detect Edges. Set the blend mode to subtract.
Add the adjustment layer, posterize. Adjust the levels for taste. My example uses 4.
That's it. Now you have a basic cartoon stylized picture. You can use all sorts of additional methods from here. But this seems a good starting point. Hope you find something useful in this. Cheers.

Here's a great demo of Behringer X-touch mini in use with LR that may visually address your question. 
 
Not having any detailed knowledge of the midi interface/specs, I can't speak directly to your question of 128 value support. However, it would seem the actual resolution supported is greater than 128 discreet values based on actual usage. As Dan Moore writes, "the difference now is that midi controllers like the X-Touch Mini use encoder knobs which turn indefinitely and use an LED fan to indicate value. When connected to Lightroom using Midi2LR the encoder knobs update from photo to photo based on the given property." Effectively, using midi2lr and Behringer X-Touch Editor (PC only), one can set arbitrary value ranges: 0 to 100, -100 to 100, 0 to 16,387 with step/scale values. The step/scale effectively controlling the "sensitivity" of the knobs. Since the knobs turn indefinitely the mapping software controls the range of values being transmitted.
 
Hopefully, the demo video answers your question on the mapping of controller knobs to input resolution.

Mystery solved. I do indeed have a symlink defined for the Applications folder. While not a problem for the retail versions, evidently this is an issue for the betas. Hopefully, this will be addressed in an upcoming beta release. For now, I have moved my Applications folder to the volume root to be able to run the betas.
