Compact, rugged, and highly versatile organismic synthesiser, featuring four non-linear tone generators (referred to as voices), FM synthesis capabilities, a complex HYPER LFO, a MOD DELAY with self-modulation, and a built-in distortion, making it ideal for experimental sound design, live performance, and studio work.
At a glance
- Four non-linear tone generators (voices) with behaviour resembling vintage electric organs, designed for organic sound interaction.
- FM synthesis mode where each voice acts as an independent FM operator, with decreasing impact as the envelope decays.
- HYPER LFO combining two LFOs through summation or multiplication, offering sync mode and modulation options for voices and MOD DELAY.
- MOD DELAY with self-modulation, allowing the delay output to modulate the sample rate, producing unique effects.
- Built-in distortion that interacts with the delayed signal for layered sound shaping.
- Tree-like voice structure dividing the four voices into two pairs for complex sound architecture.
- Compact, rugged design suitable for live performance and studio use, with balanced output dynamics and frequency response.
The Soma Lyra-4 is a compact, rugged, and highly versatile organismic synthesiser, featuring four non-linear tone generators (referred to as voices), FM synthesis capabilities, a complex HYPER LFO, a MOD DELAY with self-modulation, and a built-in distortion, making it ideal for experimental sound design, live performance, and studio work.
Organismic Design and Non-Linearity
The term "organismic" refers to how the Lyra-4’s modules interact in a way that mirrors organic, living systems. Its four tone-generators, or voices, are designed to behave in a non-linear manner, unlike traditional subtractive synthesis oscillators. These voices resemble those found in vintage electric organs and don’t follow typical control voltage behaviour. This unique design allows for rich, evolving sonic textures.
Voice Structure and FM Synthesis
The Lyra-4’s four voices are divided into two pairs (12, 34), forming a tree-like structure. They can operate in either an electric organ mode or as individual FM synthesis operators. In FM mode, each voice acts as a separate operator, and its contribution to the overall synthesis diminishes as the envelope decays. This dynamic interaction between the voices offers a wide range of sound design possibilities.
HYPER LFO
The HYPER LFO is a sophisticated low-frequency oscillator that combines the outputs of two simple LFOs, either by summing or multiplying their frequencies. It includes a sync mode and can modulate selected voice pairs or the MOD DELAY, allowing for complex rhythmic modulation patterns.
MOD DELAY and Self-Modulation
The MOD DELAY is a unique delay effect with feedback, offering a distinct feature where the output signal modulates the delay’s sample rate. This self-modulation results in distinctive, evolving delay effects, adding depth and texture to your sound.
Built-in Distortion
Following the delay, the distortion circuit not only adds character and grit but also allows the delayed signal to influence the distortion, creating further layers of sonic complexity.
Professional-Grade Performance
Despite its experimental nature, the Lyra-4 is a professional instrument, delivering a balanced frequency response and output dynamics suitable for live performance and studio recording without the need for additional post-processing. Its compact size and robust design make it easy to transport, while its unique sound capabilities offer a different experience when using two Lyra-4s compared to a single Lyra-8.
