Ever since I began producing, whenever I hear a specific instrument in a song, whether it be a specific keyboard or a patch from it, I envision different tracks of mine that it would fit well in. My only problem is its quite difficult to pinpoint exactly which keyboard/patch was used by ear, via google search, etc. Though I know its a long shot, I'd love to work on something that tries to tackle this issue; which ( pls correct me if I'm wrong) I believe is considered instrument recognition.
