Sound Radix have announced an early access promotion for Radical1, available for $129.00, increasing to $199.00 after the promotion.
Radical1 is Sound Radix’s first step into a vivid, colorful world of additive synthesis. Created for musicians, sound designers, and curious creators, it blends spectral control, deep modulation, and musical movement into an instrument that feels alive under your hands.
This is the Radical1 Preview Release, a continuously evolving instrument that invites you to explore its universe from the very beginning. The Preview Release is available to explore right now – both as a free trial and at a discounted early-access price. If you choose to purchase it during the preview, your license automatically includes the full version when it ships, complete with all factory presets. Until then, you get immediate access to everything already available inside the Preview.
Radical1 introduces a clearer, more intuitive way to work with additive sound. Layers, modules, blocks, and modulation paths are displayed exactly as the instrument plays them. No hidden routings. No guesswork. You always see what is shaping your sound.
Movement becomes easy to follow and fun to explore. Every modulation connection is visible in real time, so you can design complex behaviors with confidence and understand your patch at a glance.
Starred parameters highlight the controls you reach for most often, keeping essential adjustments ready on the surface while deeper options stay neatly organized below.
This transparency creates a workflow that feels fluid, musical, and deeply connected to the sound you’re shaping.
In Radical1, the visual story and the sonic result stay perfectly in sync.
- Expressive Additive Engine – Radical1 builds sound from harmonics you can sculpt, bend, and animate. Create tones that evolve like acoustic instruments, shimmer with spectral color, or punch with modern electronic character. Everything reacts musically to your touch.
- Infinitely Modular for Living Movement – Use as many layers, blocks and modulators your imagination (and CPU) calls for. Shape subtle variations or sweeping transformations. From simple patches into expressive, evolving sonic stories.
- Spectral Tools with Musical Intent – Work directly at the harmonic level with shaping oscillators, spectral filters, and time-varying modifiers. Craft sound from the inside out with precision and playfulness.
Radical1 is available to Mac users (VST3, AU and AAX) and requires an iLok account. A Windows version is in development and should be available le early 2026.
