Select your computer's OS (macOS/Windows) and then continue at "After connecting"
The first thing you will need to make sure is that both your smartphone and your computer/laptop are in the same network.
Example: Your phone is connected to your router via WiFi(WLAN) and your PC/Mac is connected to your router via LAN or WiFi(WLAN).
After launching the app on your phone, select your OS (Windows or macOS) below.
You need to download and install an additional driver available at humatic.de The download link is located below "Downloads" in the 5th line.
After installing MIDIHub, launch it. Check whether your phone's showing is on the left. If not, reboot your PC.
Check if another application is already accessing MIDIHub. If the upper-right text says "Loaded by MIDIHub" or the application you wanna use it with, you can continue with Step 3. If it mentions any other software hit the triangular exclamation point warning sign thingy right next to it and add the .exe you don't want as an exception. You might have to repeat this until you get "Loaded by MIDIHub" or Traktor, Ableton, Maschine, ...
Drag and drop a virtual cable from the port symbol on the tile of the phone to "Port 1" on the right. Remember the port name you picked and close the software.
Proceed with "After connecting" down below.
Open up the Maschine sequencer and open up the Audio and MIDI Settings.
In the MIDI tab, search the port (e.g. "MIDIHub Port 1" or "phone session"), set it to "On" and confirm with "OK"
Close the settings and find the gear icon in the transport control panel. Enter "MIDI Scene Change" and set the source to your session. Set the type to Program Change and the channel to Ch. 1 - just as I did in the screenshot.
That's all! You are ready to go, I hope you'll enjoy this little piece of software. Maybe you wanna include the scene MIDI setting in your default project so you don't have to set it up manually every time.
