Metamyther & Kevin Keller: Solar 42N—A Synth That Breathes in Nebulae

In the atmospheric haze of Metamyther’s new Synth Showcase, we drift alongside ambient composer Kevin Keller as he navigates the Solar 42N—a synthesizer with the gravitational pull of a dying star. Through tactile oscillators, spectral drones, and light-sensitive magic, the Solar 42N invites us into a world where sound is less played than conjured. This is not a technical exposition but a poetic immersion, guided by creators who shape space and silence for a living. Expect chords that shimmer like heat on asphalt and performances that slip between the cracks of time.

Dawn of the Solar 42N: Constellations in Circuitry

The Solar 42N is not merely a synthesizer—it is a gravitational well for sonic explorers, introduced here as the centerpiece of Metamyther’s new format. With composer Kevin Keller at the helm, the instrument emerges as a vessel for ambient narrative, a weather system of oscillators and mysterious modules.

From the outset, its architecture is described as a lattice of 42 oscillators, grouped into modules, each capable of birthing drones that hang in the air like dust motes in a sunbeam. The Solar 42N’s unique organization—five tunable sawtooth drones per module—suggests a machine built for harmonics and resonance, rewarding those who seek to shape chords that bloom and decay in organic unpredictability.


Kevin Keller’s Sonic Rituals: Live, Alone, and Altus

Kevin Keller’s relationship with the Solar 42N is more than technical—it’s devotional. Performing at the Brooklyn Experimental Electronic Music Show with nothing but this synth, Keller transformed the stage into an environment where each note was a deliberate act of creation. His recent album, Altus, finds its pulse in the Solar’s circuitry, with the instrument serving as both palette and brush.

Keller’s approach is grounded yet exploratory; he describes building drones not by overwhelming complexity, but by distilling chords to their essence—a root and a fifth—letting the instrument’s natural character resonate. Through this, the Solar 42N becomes his co-conspirator, guiding compositions that shimmer with restraint and intention.


Organic Machines: Playability and the Art of Evolving Atmosphere

The heart of the Solar 42N beats with organic, ever-shifting sound. Its playable interface—pressure plates, joystick, and light sensors—invites the performer into tactile dialogue, where timbre and modulation are shaped by gesture and light. Each blue-knobbed drone module hums with sci-fi unpredictability, while sequencers bubble with classic space-music ostinato, conjuring the ghost of Tangerine Dream.

The instrument’s dual filters, LFOs, and a constellation of effects cartridges (with names like Infinity and Cathedral) turn every movement into a shifting landscape. The interface is not a glass barrier but a canvas for evolving atmospheres, where melodies bend like rays through fog and every live tweak becomes a ripple in sonic space. Some textures, some moments—like the shimmer of the Infinity delay—simply must be heard to be believed; the video itself becomes a portal into these subtleties.

They make these more like space sci-fi.

Composing Beyond the Keys: Techniques for Uncharted Harmonics

Keller reveals that the Solar 42N’s true power lies in its ability to break the tyranny of the traditional keyboard. With modes ranging from Ionian to Japanese folk scales, the instrument’s touchplates become a garden of unexpected harmonies. Keller chooses scales by feel, not by theory, letting intuition dictate where each drone lands in the harmonic nebula.

Composition and improvisation intertwine as the interface dissolves boundaries—arpeggiators remember fleeting gestures, while tuning is accomplished by ear, not algorithm. The absence of MIDI is not a limitation but an invitation to manual synchrony, to perform with the instrument as a living partner in exploration. Here, the Solar 42N encourages sonic risk, rewarding those willing to wander off the map.

A Living Demo: The Solar 42N in Full Bloom

The video’s closing moments are a river of live sound, where Keller demonstrates the Solar 42N’s full bloom. Layers of drones shift like auroras; sequencers flicker, and effects swirl into infinity. Techniques unfold in real time—arpeggiators are silenced, drones take center stage, and the entire mood morphs as if the synth itself were inhaling and exhaling new atmospheres.

There is a tactile joy to panning, fading, and sculpting the mix on the fly. The Solar 42N is celebrated as a truly standalone instrument, a self-contained galaxy for those who crave both control and surprise. Watching this performance, one senses that some mysteries can only be experienced in the moment—the true resonance of this instrument lingers long after the final note fades into silence.

So it was really kind of freeing to make a number of pieces on the record, which was literally just a kind of a structured improvisation in…
