Are these keyboards out of stock at the moment ? and if so will there be more coming ?
Yeah, looks like they are only listed on the Summer Sale Page under "Hardware" bundles here:
Hardware Offers (native-instruments.com)
Since they are selling them in Hardware/Software Bundles for the Summer of Sound Sale, pretty sure they are in stock... I noticed they removed the links to the product pages for the S-Series from the Midi Keyboard page, but probably to drive purchasers to the "Sale" and steer them away from buying just the "Controller". But in removing the links to the S-Series product pages, they removed the ability to download any manuals/cheat sheets etc. Kind of a weird move!!
Hmm I don't see the black ones anywhere, just the grey and pink ?
