Questions about Hercules DJControl Inpulse 200 MK2

I could not find any specific information about the DJControl Inpulse 200 MK2's compatibility with FL Studio. However, the controller is compatible with software such as Serato and DJUCED, and may work with FL Studio if you use a custom MIDI mapping. I recommend that you consult the official FL Studio documentation for further details on how to configure the controller.

No, you need a DJ programme. Recordbox is free, you can use it. But you can't connect Spotify. Only mp3 files or soundcloud or tidal similar.
