Problem with mapping midi devices (Keyrig 25 & APC40 ii)

I have an M-Audio Keyrig 25 and an Akai APC40 mkii and neither one of them will map to VCV rack. The APC40 faders work, but all of the sliders are mapped to the same channel. The Keyrig 25 does not even get recognized. Is there a way to make these work?

Which module do you use?
