This guide is set in the web DAW Beepbox, specifically a mod of it titled "Abyssbox" by choptop84, but it can be utilized for other software. The example we are going to be deconstructing is track one of At Symbol EP, which is available on this website for listening. I have never put my process into words before now, so please excuse if it is not perfectly cohesive.
Synthesizing
The base of the song is mainly synths created using frequency modulators or FMS. Above is a chord progression that plays at the start and throughout the song. settings are important! I recommend you put your own twist on it, dont be afraid to get creative with avant-garde, and tweak it however you find best suits you.
Firstoff, you can set your instrument to either FM or FM 6-op, it doesn't really matter, but i will be using FM. i like to mess with the fade a bit, For this synth specifically, it does not fade at all to attribute its harsher sound.
