this is a video by andrew huang. this is the audio interface i use and he explains very well why it is very very very great. i have a hard time explaining it, so here is a great video to do it for me. you should watch a lot of his videos. he has a lot of great content and really opens up the brain part of the mind about how to write music, “B” parts which are where the chord progression changes to a new, related part… and a lot of other interesting things that will help to see writing and producing music in a new way. enjoi i hope
