Remaking the keys synth from the 1998 song "Turquoise Hexagon Sun" by Boards of Canada can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Turquoise Hexagon Sun" keys patch and play this iconic sound on most hardware or software subtractive synthesizers (Serum, Vital, Pigments, Prophet, Korg, Moog, etc). We've included the preset download directly for your convenience, but we strongly recommend you use our programming tutorial to recreate it yourself.
Original Audio
Boards of Canada’s “Turquoise Hexagon Sun” opens with a haunting bell-like synthesizer sound that establishes its ethereal atmosphere. This timbre is achieved with a simple sine wave, subtle unison, and heavy reverb. The synthesizer appears immediately at the track’s start, dominating the mix before evolving into layered textures.
