Hi and welcome to Arturia forums.
I don't know if i can help.
But have you followed the manuals to set up you Minilab MKII and your Analog Lab? How is your settings in your Analog Labs audio and MIDI setup page?
Also download the MIDI Control Center software and it's manual.
I suggest you read in all the manuals first. Here is the download page:
https://www.arturia.com/support/updates&manualsAFAIK then Analog Lab should recognize your controller and set the selector in the lower toolbar of Analog Lab to Minilab MKII. This way you controller should work out of the box. The Midi learn icon is'nt visible in this mode, as you can't use it in this mode.
When you select "Default" as controller, then it's another setup, than using the Minilab MKII. So switching between the 2 setiings will give different results.
If Analog Lab does'nt recognize your controller automaticly and set the controller selector to Minilab MKII, then perhaps it's an error in Analog labs Audio and Midi settings.
Return if this and reading the manuals does'nt help.
