Engine & Synthesis

Patent-pending additive engine capable of generating tens of thousands of oscillators in real time with minimal CPU usage
Clean, accurate frequency response up to Nyquist with no aliasing and no oversampling
Morphing Fluid Oscillators for smoothly transitioning timbres and continuously reshaping harmonic structures
Direct Spectrum Drawing generators for hands-on harmonic sculpting
Spectral Sample Resynthesis for turning recordings into fully controllable additive structures
Spectral shaping tools, harmonic modifiers, and a real-time spectral display
Polyphonic, per-voice processing and modulation
Ultra-fast, sample-accurate envelopes for sharp transients and detailed expressive control

Workflow & Modulation

“What You See Is What You Hear” workflow with fully visible layers, modules, blocks, and modulation paths
Unlimited layers for building complex, multi-part patches
Unlimited modulation sources with clear visual routing and instant feedback
Starred parameters for immediate access to your most important controls
Scalable, high-resolution interface designed for clarity and speed

Built-in MIDI Effects Rack for arpeggiation, sequencing, note shaping, and performance behaviors
Time-Domain Audio FX Rack for filters, dynamics, spatial tools, and creative processing
Spectral Block FX for harmonic-domain bending and spectral transformation
Modular signal flow that lets you place spectral audio effects exactly where you want them

Formula Blocks for writing custom DSP code directly inside Radical1 (tone shaping and synthesis processing limited only by imagination)
Direct access to internal modulation streams, harmonic structures, and spectral domains
An expanding collection of modules and blocks for advanced sound design
