I have recently downloaded and I tried to configure the buttons to the correct ones. The X, Circle, Square, and Triangle button work perfectly, but then I try to press the D-Pad for the Up, Down, Right, and Left it says wrong for all of them. I'm not really sure how to fix this problem. I am using the Xbox One controller for windows. Is it the controller that is making it like this? Is there a separate controller that works with windows and can work properly with this game?

the game is NOT programed as the PS diva games so therefore you cant use the arrow keys as the XO/\ and square the game is designed as the Arcade which you only have the 4 big buttons and the sliders thats all, unless the KHC master makes it like FT where you can use the arow keys to spam easyer and not kill your fingers on every 10 stars song and your mood for playing goes from 10 to -10 in 3minutes

you can use Xpandder so you use Xbox one controller right?
so first Triangle,square,X,and O is use in Xbox is Y,X,A,B right
and for D-PAD you use Xpadder kinda like you setting again Triangle,square,X and O in D-PAD

for slider you can use LB and RB

I already downloaded xpadder but it only let you choose on W S A D and even though you try to change it to different button (refer to keyboard) it will not going well with you. My best, I got 2 keys working which are x and y but the other are not respond and only give you "wrong" result in the game T T

Ps. I'm using Xbox one controller

Some things have changed since you created this tread. Update PPD to latest version, you should have CSInput Mod. Activate it and it will allow you to dualwield (use arrow keys for circle, cross etc.). Notice that this mod will block uploading you result on server.

Hmm

I found the fix. Got to mods and turn on CSInput and then it will work.
