Materia Prima is an expressive, multi-layered sound design engine and Kontakt library built for composers and sound designers who enjoy shaping, layering, and exploring sound. It blends sound design features with a rich library of ready-to-play presets — from cinematic pads to evolving pulses, dirt-ready basses, lush keys, organic textures, and much more.

At its core, Materia Prima combines three independent sound layers per voice with extensive modulation (Pulse Engine), filters, and a flexible effects suite — giving you complete control over every aspect of your sound. With its drag-and-drop sample support, you can sculpt custom sounds in minutes, or use the included waveforms to build entirely new patches.

Key Features

Multi-Layer Engine: Three dynamic sound layers with independent envelopes, tuning, and routing options.
Inspiring Presets: Over 230 presets & multis spanning bass, pads, synths, pulses, leads, organic elements, percussion, FX, plucks, and keys. Includes many multi-sampled (velocity and round-robin) instruments.
Robust Effects Suite: 16 simultaneous processors including distortion, modulation, delay, convolution reverb (with 700+ IRs), compression, EQ, and more.
Pulse Engine: Tempo-synced LFOs and sequencers for rhythmic modulation and expressive motion.
BYOS Edition: Bring Your Own Samples — drag your own samples into one of the three layers. Features automatic root note detection and looping support. Includes a selection of WAV files to get you started, including simple waveforms and samples from the Materia Prima library presets.
Performance Controls: MIDI CC mapping, user-configurable aftertouch, and pitch-bend support for expressive playability.

Who Is It For

Materia Prima thrives in soundtrack, ambient, cinematic, electronic, and hybrid production workflows — ideal for composers and producers who want deep sound design capabilities and inspirational libraries in one integrated engine.
