USB Mixer , Audio Interface Combo Hardware ?

New to recording, sorry for a basic dumb question …

  1. Are there USB Mixers that have MIDI ?

  2. I use Yamaha MW 8CX that works fine except when I need to record MIDI since it has no MIDI ports. So I switch M-Audio Fast Track Pro.

Wondering if I can avoid switching back and forth. .Are there Mixers that also have MIDI and if so what are they. If not, how can I record both audio and MIDI from external keyboards
