Icarus 3: Additive Synthesis Beyond Sine Waves (Tutorial)

Website: https://www.tone2.com/icarus.html Unlock the full potential of Additive Synthesis without the limitations of standard synthesizers. In this tutorial, developer Markus explains how Icarus 3 allows you to use any waveform—not just sine waves—as the basis for additive synthesis. Learn how to build complex, disharmonic, and unusual sounds from scratch. We cover the two distinct ways to use additive synthesis in Icarus: using the real-time Oscillator Modes for disharmonic textures, and using the Wavetable Editor to draw precise harmonic partials. Video Chapters: 0:00 - Introduction by Markus 0:35 - Sound Demos (What is possible?) 2:07 - The Icarus Difference (Smart Phase Alignment) 2:49 - Building a Sound from Scratch 3:43 - The Additive Modes (Bell, Stereo, Random) 4:20 - Using the "Spread" Knob for Tuning 5:50 - The USP: Using Non-Sine Waveforms 8:22 - Method 2: The Wavetable Editor (Drawing Partials) 9:58 - Harmonic vs. Disharmonic Ratios Explained Why Icarus Additive is Different: Any Waveform: Unlike competitors, you are not limited to sine waves. Combine additive synthesis with wavetables, samples, or FM. Smart Phase Alignment: Algorithms automatically prevent the volume peaks and phasing issues common in other synths. Dual Workflow: Use "Modes" for wild, disharmonic experimental sounds, or the "Spectrum Editor" for precise, organ-like harmonic structures. About Icarus 3: Icarus 3 has been extended with powerful additive synthesis modes. These modes drastically extend the sonic range, especially with disharmonic and unusual sounds. Unlike competing synthesizers, our additive synthesis can handle any waveform or synthesis mode.
