Hey folks, I am a pretty new electronic producer and am still getting my head around how to take a sound that I have heard and recreate it myself. That being said- I was hoping for some direction on how to get as close to this main chord/ organ sound as possible-

I can't post a link as it's my first post, but "charlie brown sad amv edit" on youtube will bring it up as the first video. The sound is around 24 seconds into the video.

Any help or advice appreciated!
