midi usb problems

Hi, I currently, am looking to buy this audio interface http://www.musician… Tascam US-1800 USB 2.0 Audio/MIDI Interface | Musician's and I currently have a USB MIDI Keyboard.

I need some help setting up a midi usb cable with my current setup. I have a KORG d1200 (which is acting pretty much as a phantom power for my mic), and i HAD it hooked up through its headphone jack going to my computer which is running adobe auditon 3. I decided to up my sound quality by getting a MIDI to USB cable (M-Audio).

heyya I'm just starting out, but how does a midi usb cable work?

i mean, all the voices transmitted from the keyboard to the computer (software sequencer, eg. sonar) thru the usb?

so the usb end goes into the usb port whereas the other split end goes into the keyboard out 2/R?

heres the link to the forum post which got me thinkin, heheh
