I'm Not Even Human ( a film that I made in 2018 ) has an original score written by me. This original score is also the first time I used MIDI to compose music instead of playing it on the electric piano. The first song "Explosion" was originally composed and recorded using the piano, but the sound quality of the piano was nowhere near where I wanted it to be for the movie. So for the first time I touched MIDI and redone the song in MIDI, which sounded great. So I made all of the original score for the movie in MIDI apart from 3 songs. The Bill's Into was recorded with live guitar. Abstraktation was improvised on the piano. And the final Bonus Track was recorded the same way as my album The Pentas.
