Here are some of the things I learned about moving Instruments Within Stereo Field
1) To move an instrument left to right: pan
2) To send an instrument backwards: EQ (high freq. roll-off), reverb
3) To bring an instrument forwards: EQ (increase high freq.), compression
4) To widen the image of a single instrument: delay
Here is a video of Kanye West using a drum machine while making the beat to his song Good Life featuring T Pain. I choose this video because in my Computer Music class I actually used a drum machine to make the beat for my first project. Also Good Life is one of my favorite songs by Kanye and I never knew he used a drum machine on the beat.
