Worked immediately with the IK Multimedia Hammond B-3X Expression pedal for volume, CC values on the same software instrument track. There is a tricky solution though to get it working with a Neural DSP amp plug in (for example the wah wah pedal function) with a guitar (audio). I had to contact Neural DSP for the Logic Pro config, and the instructions on the two track method to get the wah wah working.

From Neural DSP support:
- Click on Logic Pro > Preferences > Advanced Tools and make sure "Control Surfaces" is checked.
Please also enable Expert View enabled in the Controller Assignments:
- Click Logic Pro > Control Surfaces > Controller Assignments and now select Expert View.
- Make sure your controller/expression pedal isn't assigned to anything else. (It's best to just delete all existing assignments if they are not important.)

Within Logic Pro, in order to control your plugin via MIDI, there are a few ways to perform MIDI control. You may choose which one works best for you;

1) A Software instrument track:
Please launch Logic and select "Software Instrument" instead of 'Audio'.
You would have to load the plugin as an AU-MIDI controlled effect.

After you have selected that, click on the drop down menu for "Instruments" and at the bottom of the list, you'll see "AU MIDI Controlled Effects". Click on that, and look for Neural DSP > (for eg) Archetype Gojira > Stereo.
Then, please enable the Side Chain audio input to this 'Instrument' track. Just click on Side Chain on the top and click on your input being used for the guitar. (i.e Input 1 or Audio 1, whichever you are using for your DI track)
Please make sure this track is Armed.
Note that the messages you want to use for the Neural DSP plugin are not 'hard-mapped' to other plugins within Logic.
In other words, if you find that you are still not able to use those PC messages, it may be that your DAW likely is using those PC messages for some other functions, or they are mapped to something else in your DAW/VSTs. In that case please try to clear all MIDI mappings from the Logic MIDI settings window.
:: If you're using also a MIDI controller, just right click on the thing you wish to map, i.e the Wow pedal position, and move the expression pedal back and forth/up and down. It should map it successfully right after that. You can even save this as the default map for your plugin.
Bonus tip: If you want to record that track's final output signal, you'd have to do it by sending this track's output to a Bus (i.e Bus 1), and creating a new "audio track" with Bus 1 as it's input.
To record, just make sure it is "record enabled".

2) By using the MIDI Learn feature within Logic Pro:
:: This method can also be referred to as 'hard mapping'. That means that Logic will create a link between your desired parameter and the MIDI message that you map to it. That MIDI message will not be able to be used for any other parameter within Logic or any other plugin.

Please launch Logic Pro and create an Audio track.
After the track is created, click on the "Audio FX" drop down menu and at the bottom of the list, you'll see "Audio Units".
Click on Audio Units and look for (example) Neural DSP > Archetype Gojira > Mono to Stereo.
Go to the 'pitch' component page within the plugin. (or any other page, where the desired parameter for control can be found)
Click and drag the Wham pedal (or any other parameter that needs to be mapped) and press Command + L . The Controller Assignments window will pop open.
This is the cue to move the knob/fader/expression pedal that you'd like to use for controlling the desired/adjusted parameter.
Using this method, that CC message will be 'hard-mapped' to the that plugin and for that parameter.
Meaning, if you open and select another track with the the same plugin loaded, your Expression pedal will automatically be mapped to the Wham pedal. So, this will not need to be done for every instance that the plugin is loaded.

By the way, all plugins work the same way, in terms of mapping and receiving MIDI. The method across the rest of the plugins would still be the same.

This pedal works great. I bought the UP4 to use with Amplitube 5 for the wah-wahs. I thought I would pass along what I learned getting it to work with the wah and other controls. Disregard the Dip Switch chart on the back of the UP4. Pedal is ready to go for this application. No switch changes are required. I connected the USB cable to the computer before I opened the Amplitube program so it would be detected along the A/D interface when the program is opened. Then I opened the program. In the top right (hamburger icon) open the Audio/MiDI menu. On the bottom of the menu in the center is MIDI In. Click on it and 3 selections will show. Your A/D interface, Arduino Leonardo (this the UP4 pedal) and Any. Select Any. Close the menu. Select a wah and drag and drop it into the effects chain. Right click on the wah, Click Assign MIDI>Wah>Learn Wah and it will show Waiting for MIDI Input. Then rock the pedal up and down. Wah is ready to go. Try another control. Select Uni-V (Univibe). Right click RATE>Click Assign MIDI>Rate>Learn Rate> then Waiting for MIDI Input shows, then rock the pedal up and down. It now controls the RATE (speed) of the Univibe. This how you can the use the pedal for controlling anything you want. Right click any control and do the same procedure. This is what worked for me. I hope this saves folks some time getting it up and running. Cheers

Set-up guide:

1. plug in (duh)

2. Load a neural dsp archetype.

3. Go to "settings" and select the Midi Input device "Arduino Leonardo" (I have no clue why it's called this. But it is.)

4. Right click literally any parameter within the archetype. My choice: Archetype: Gojira's FATSO MIX wah pedal

5. Let chaos ensue

The Crumar UP4 USB-MIDI pedal works right out of the box with my Korg PA5x keyboard. I plugged the UP4 into a Korg USB port, and within the Korg system, I programmed the UP4 to function as a wah-wah pedal, affecting the keyboard sounds. The UP4 works perfectly, and feels great. Adds a bit of personality and funkiness to the keyboard sounds.

I bought this without knowing if it would work with Bias FX2, but it works great! At first, I thought it wasn't working, but you have to make sure you go into the audio settings in Bias FX2 and fill out all the fields and check mark the pedal. The pedal will show up as an arduino leonardo midi device, because it uses the pro micro arduino board inside. It plugs into the usb port on your computer and works independently alongside your audio interface. I use the Focusrite Scarlett 4i4. I can also confirm is works in Cubase 12 using Bias FX2 as a VST plugin.
