West Coast Sine Wave Drone

Each row has a Sine Wave that goes into a Wave Shaper/Folder.
Next the signal goes into a Low Pass Gate/Filter and then into the Mixer.
Each section has a LFO to add movement to the module.

The Bottom Row has a sequencer set to a minor key scale (to add some harmonic content). If you don’t want that, then mute channel 5 of the Mixer.
