The midi mapping black UI elements have three lines, set the top row to core midi, click on the middle row, and your launchpad X should be listed. This need to be done for both midi in and out.
To assign midi mappings for the grid buttons,
- click the midi learn button on the left of the iversion UI
- press a pad on your launchpad
- press the corresponding button on Iverson’s UI
- the UI button will change colour and display a midi mapping x:xxx
- repeat steps 2 - 4 until all pads are mapped 5 click midi learn on the UI, to leave midi learn mode.
you can use the same method to assign all the buttons on the UI, except midi learn.
I hope this helps, but please feel free to ask if you require more assistance.
