I have noticed trying to add a midi fighter pro to your cart is impossible, it says you have unselected fields,
which i’m pretty sure is the cable not being chosen, L or straight angle. The selection drop down is not there.
First it gave me an error then I tried again and it worked. Have you tried with different color knobs and buttons, maybe they’re out of stock on something you’ve selected. It shouldn’t give you an eror though so I would still email orders and let them know.
You can change the color of the buttons’ “rings” when you get it. They just snap on and off. Actually, I think there is a video somewhere on here showing exactly how to do it, and if not I know I saw it somewhere on the web.
as i wrote before, if you have troubles adding a product to the cart or want detailled information about what can be bought: shoot an email to orders@djtechtools.com and wait for their response.
