Nonlinear Labs C25 Next-Generation Expressive Performance Synthesizer
Superbooth 2026: The Nonlinear Labs C25 is a 48-voice performance synthesizer built around the Phase 22 synthesis engine, combining expanded physical controls, a touchscreen interface, and deep expressive playability.The C25 synth is an evolution of Nonlinear Labs’ C15 platform. It features the Phase 22 synthesis engine, which combines phase modulation, FM-style synthesis, waveshaping, physical modelling, and subtractive techniques within a single architecture.
The system integrates a redesigned control surface with a 7-inch touchscreen, dedicated hardware buttons, encoders, and performance controllers. It supports a 48-voice architecture at 48 kHz, or 24 voices at 96 kHz, and includes split and layer modes. The instrument also features onboard audio recording capability, capable of capturing extended lossless recordings.
Performance control is a central design focus, with a keyboard that supports polyphonic modulation through key position, velocity, and aftertouch. Additional controllers include a bender, lever, dual ribbon controllers, pedal inputs, and CV inputs, all assignable to modulation destinations within the synthesis engine.
The interface is designed for direct access to synthesis parameters through a combination of hardware controls and a touch-enabled display, while maintaining a structured navigation system for deeper editing and preset management.
Features:
