Supra by W. A. Production is a monophonic hybrid granular synthesizer that combines analog-inspired character, FM synthesis, and grain manipulation for expressive, evolving sounds. Developed in collaboration with Algebra Within and producer and DSP programmer darkInteger, Supra moves from deep bass drops and aggressive FM growls to shimmering bells, piercing sirens, and atmospheric clouds.

Its six-stage signal path starts with a triangle-core oscillator featuring asymmetric diode waveshaping and subtle pitch drift for vintage-style movement and saturation. A high-frequency sine modulator adds harmonically rich FM tones, while the granular engine captures the carrier signal and transforms it into crossfading, pitch-shifted grains.

Shape the results with a state-variable filter that morphs continuously between lowpass, bandpass, and highpass responses. A resonant comb filter introduces metallic, string-like textures, with feedback compression controlling peaks. Stereo auto-panning and a pitch-shifting feedback delay complete the chain, creating spacious movement and cascading shimmer trails.

Two master macros let you transform multiple parameters together, turning sound design into a hands-on performance. Drive the macros with dual customizable LFOs or adjust them manually to reshape filter tone, granular behavior, and delay feedback in a single movement. Dual randomizers add spontaneous variations, including note-triggered changes to LFO shapes, speeds, and depths.

With a clean, single-page interface and factory presets for quick inspiration, Supra makes it easy to explore everything from focused electronic basses to unpredictable granular textures.
