Synapse Audio Obsession: 60 Cinematic Ambient Presets Demo

video upload by Anton Anru

"🌃 Synapse Audio Obsession - Posthuman Dreams is a collection of 60 dark cinematic ambient presets. It includes: 8 Basses, 9 Keys, 9 Synths, 8 Leads, 7 Pads, 5 Strings, 5 Drones, 9 Textures.
📺 The soundset draws inspiration from sci-fi movies, cinematic soundtracks, dystopian worlds, urban landscapes, noise ambient albums, experimental modern art, and contemporary sound design.

📦 The presets are available here: https://antonanru.sellfy.store/p/obse...

📼 Built around the concept of imperfection, the collection blends gritty, lo-fi textures with constantly shifting timbres shaped through deep modulation.
The result is a living, breathing set of sounds—expressive, characterful, and capable of adding a distinctive atmosphere to any track, live performance, or visual project.

📻 The timbral range is wide and diverse, covering dark, noisy, lo-fi, retro, romantic, melancholic, nostalgic, atmospheric, detuned, cold, distant, dull, massive, epic, bright, orchestral, distorted, metallic, tense, atonal, non-harmonic, FX-like, evolving, and sweeping textures.

🎛 All patches are velocity-sensitive. The ModWheel enhances expressiveness by adding motion and tonal variation—brightening the sound, introducing vibrato, shifting timbre, or adding extra movement for dynamic and engaging performance.

💡 Ensure that you are using the latest software version.
To add presets to the collection, open the plugin Browser, click Menu in the upper left corner, then select Import Folder, and specify the folder on your computer."
