Tascam 424, Electro-Harmonix Pulsar, Digitech Whammy 5, Strymon Volante and BigSky // Tremolando 

Use stereo or headphones for the best experience.
I recorded 3 intervals from the Sequential Prophet Rev2 to track 1 to 3, track 4 is used as a noise track. I'm using the Electro-Harmonix Nano Pulsar to heavily modulate the audio.
About halfway I'm pitch shifting the audio with a Digitech Whammy 5 that is hidden under the table.
The Strymon Volante and BigSky are added to enhance the ambience.
