The clue is in the title really! Ambient drone using Warp Core, and also the Surge XT wavetable VCO.
The constant droning chord notes are made by feeding Bogaudio Polycon into a quantiser, then the poly channels of VCAs are slowly modulated to fade notes in and out. Supermassive is also used on both VCOs, if you don’t have Host-FX just patch an extra Plateau instead. Also, the patch is muted when it loads, click the top button to automatically fade in and start recording, the lower button is for fade out/stop.
