This 4-second stereo chord swell features an F Major 7 chord built from five notes layered with seven detuned sawtooth voices each, creating a thick supersaw texture with wide stereo spread. A 4-pole low-pass filter gradually opens its cutoff from 150Hz to 6000Hz, producing a smooth brightness swell. The amplitude incorporates a 3-second attack and 0.8-second release envelope combined with a sidechain pump synced to 128 BPM, adding rhythmic ducking typical of progressive house. The final sound is saturated for warmth, high-passed above 30Hz to clean sub rumble, and normalized to -3dB.
This chord swell suits progressive and melodic house productions at around 128 BPM. It works well as a lush atmospheric layer during builds or drops. To fit in mixes, balance its thick harmonic content with bass and percussion, and consider additional reverb or delay for depth. The sidechain effect helps it groove with kick-driven rhythms without overpowering low frequencies.
