Synthwave chords use major progressions voiced on filtered analog-style pad synths

Synthwave chord progressions typically use major keys for upbeat tracks (minor/modal for darker variants). A representative upbeat example is D–D–A–G, D–D–G–Em. Sound selection matters as much as the notes: chords are played on analog-emulating synthesizers (Oberheim-style, e.g. the free OB-Xd) using pad or saw patches, with the filter rolled off to remove harsh highs so the pad sits warm and behind the mix. Nailing this pad sound, alongside the drums, is one of the two most important steps for the Synthwave vibe. Free analog emulations reach the sound without vintage hardware.

Examples

Chord progression: D(x2) – A – G, D(x2) – G – Em in D major. OB-Xd preset ‘Pad_Saw’ (Bank 023), filter adjusted to remove most high-end for a soft pad.

Assessment

Write a four-chord progression in a major key suitable for Synthwave. Choose an analog-style pad patch and describe the filter setting that makes it sit warmly behind the mix.
