For my Coursera Peer: the three part structure is here. House tracks are not supposed to have a chorus-verse structure but a repetitive circular structure with parts that differ only for dynamics. The synths and the "music" sample are audio tracks. There are delays here and there and send 1 is max for live's convolution reverb. Most of the stuff is panned. The flute line comes from an audio to midi conversion. The sound of the flute is a flute phrase that was sliced and replayed. There is a very light compression on the master. Thank you
