Use it as a USB/MIDI controller to get +16 knobs for instant access to whatever synth/FX parameters you map it to.
Same with those 16 pads, which default to Note sending but you can reconfigure them (using Arturia's MCC application) to send MIDI CC to toggle whatever parameters you map them to or mix'n'match, some pads sending notes with velocity and aftertouch and others sending CC, PrgChg, etc.
If you have hardware, you can use it standalone both as a MIDI (DIN) controller, or as a MIDI USB-to-DIN "adapter" and/or CV output, if you have hardware needing CV control.
Then there's the built-in sequencer... which you can use it standalone (no computer required) to control hardware or even softsynths/iOS, etc.
Just read it's specs, understand what it does, look at your own setup and see where it can fit
Needless to say: you don't need to use all of its features, just the ones that are useful to you ...at that time, which may change in the future and you may then find the unused features now useful, in a new setup.
