Sound that moves from the inside

The Vintage Synth from a
Parallel Universe

Imagine early synthesizers took a different path. Instead of subtractive synthesis, engineers at the time decided to build sounds up, one harmonic at a time. Additive is the classic instrument from that history. It is the one we never got to see.

Shape your sounds from within

Additive makes that other approach intuitive and fun. Set each harmonic individually, then shape how it moves over time. Some can pulse together while others drift, shimmer, or move in the opposite direction. Rather than sweeping a filter across a sound, you shape movement directly within its spectrum. Start with a simple harmonic structure and turn it into something rich, expressive, and full of character.

Features

Set Every Harmonic

Build your sound one harmonic band at a time, or start with a standard shape or a randomly generated starting point. You can still change each band to exactly where you want it.

Move Every Harmonic

Set the movement of each harmonic independently: its depth, phase, and rate. Some can pulse together while others drift, shimmer, or move in the opposite direction.

Cutoff and Resonance, Uncoupled

Bands and Slope set the spectral roll-off. Bulk is a resonant peak with its own Position, Width, and Height. Place it anywhere in the spectrum, even above or below the roll-off, and move the two independently of one another.

Morph Between Spectra

Draw spectrum A and B, then Morph between them by hand, with an LFO, an envelope, or the performance controls. A note can begin as one sound and become another.

Modulation for Every Band

Four LFOs and four envelopes give you plenty of ways to animate the spectrum. Draw LFO shapes, sync them to tempo, and send modulation to harmonic movement, Morph, resonance, effects, or one another.

Harmonics Beyond Pure Sine Waves

Character, detune, chorus, drive, and stereo give the harmonics extra character, attitude, and depth. Go from analog-leaning to strange, distorted, or otherworldly.

Play the Spectrum

Assign brightness, movement, Morph, or anything else to the XY pad and the Z slider. Play the spectrum by hand, with Z responding to your mod wheel or the velocity of every note.
