Last FAWM, someone created a challenge to use sounds from the BBC Sound Effects library (http://bbcsfx.acropolis.org.uk/). There is a ton of material there - worth checking out. This song uses two samples from that site - cans on a conveyor belt and an ICU ventilator. Other than the samples, all the music was generated by converting the sample of the cans into MIDI tracks, then picking some instruments for the MIDI notes. I did delete some of the notes, and shifted octaves - but I didn't add any notes.
I worked on this yesterday - it was International Strange Music Day. Check the tag for other songs.
Please keep your comments respectful, honest, and constructive. Please focus on the song and not the demo.
