SOMA Laboratory's Lyra-4 is essentially half of the legendary Lyra-8 squeezed into a backpack-friendly package that weighs just 1.2 kilograms, making it one of the most portable entry points into the brand's distinctive organismic synthesis philosophy.
The heart of the Lyra-4 is its four analog oscillators arranged in two pairs, each with independent tuning controls and the ability to work in either electric organ mode or FM synthesis mode where the envelope acts as a separate FM operator. You interact with the synth through four touch-sensitive contacts that trigger envelopes with fast and slow release modes, plus a central Hold knob that lets you lock in static drone amplitudes and create the kind of sustained, evolving textures the instrument is built for. The Hyper LFO is where things get interesting—it combines two simple LFOs through summation or multiplication to generate complex modulation shapes, which you can route to either the voices themselves or the onboard mod delay for self-modulation feedback. The signal path flows through a mod delay with its own feedback and sample-rate modulation capabilities, then into an analog distortion stage with wet and dry mixing, giving you everything from subtle warmth to dense, saturated skronk. Additional controls include vibrato for pitch warble across all voices, CV inputs for external modulation, and a Sharpness knob that morphs oscillator character between triangle and pulse waves.
The Lyra-4 has found genuine appreciation among experimental musicians and drone enthusiasts since its reintroduction, with players drawn to its unpredictable cross-modulations and the way it behaves almost like a living entity rather than a tool you fully control. Some note that the simplified delay section compared to the Lyra-8 is a reasonable trade-off for the portability, and the instrument's balanced output dynamics make it equally at home in studio recordings or live performance without additional processing. The organismic design philosophy means you'll encounter spontaneous sonic behavior and feedback loops that reward exploration and embrace a degree of beautiful chaos.
