So I just decided to buy a MIDI to USB cable and tried recording, but the sounds from my keyboard (KORG Kross 88-key) don't match. I read something about an audio interface, but I'm not sure of it's functions. I use Sony Acid Music Studio and when I play the notes are there, but not the sound I want. There's also a 0.5 second delay when I play into the computer. Any fixes, tips, or info that will help me out. I'm new to all of this.
