>>713958674It's great for Project Diva. You can do the slide notes with the FX buttons or use the knobs with this script https://www.reddit.com/r/ProjectDiva/comments/w0dc0c/the_faucetwo_sdvx_controller_actually_works_well/ii6pr4r/
You can also play DJMAX up to 6b in Steam mode and use the knobs for the side notes. I'm not sure how comfortable it would be to play like that, though.
Of course, any 4/6 button VSRG will work well with that controller too.
