After scanning for plugins Komplete Kontrol is not scanning. Im using an MPC in controller Mode and Apollo twin as an interface
I don't think MPC 2.x supports VST3 yet so if you have the latest version of Komplete Kontrol it won't appear in the MPC software as it only has a VST3 plugin.
Do you have a MK3 S-series keyboard? If you don't you could use Komplete Kontrol 2.9.6 which has a VST2 plugin. You can download it from here - https://support.native-instruments.com/hc/en-us/articles/360000313457-Komplete-Kontrol-Legacy-Installers-for-Older-Operating-Systems
