Animusic - Starship Groove (but I made the audio entirely on my phone)

The audio was made on my Android phone using Caustic. It’s a great app with VERY powerful instruments (including a rack-mount synthesizer), but sadly it hasn’t been updated since 2017. I made a half-decent recreation of Acoustic Curves too, but all the complex tempo changes make it next to impossible to sync up. Same for a lot of Animusic songs, really. The arrangement itself wasn’t made by me, but I can’t find the original author of the MIDI file. Video source:
