Please excuse the stupidity of my questions, but I am new to using VST's and computer recording. I am trying to set up my Korg M3 to act as a controller to play samples on my computer. I recently acquired Kontakt and plugged my usb from my Korg M3 directly into my computer, thinking that Kontakt would recognize it and allow me to play the samples. I could not get it to work. On Kontakt, I checked to see if there was a device for the M3 and it was blank - nothing.
Can anyone tell me what I am doing wrong? I don't have a MIDI interface, but didn't think I needed one since I always thought that MIDI can be sent through a USB cable. I have installed the M3 driver.
Please walk me through this if you don't mind and remember, I have never used a keyboard through a computer before.

thanks so much,
Dave
