Sculpt a timbre by dragging harmonic circles in a 2D space, then hear your creation played as a melody. Every concept from the course in one instrument.
In the world
A professional sound designer thinks in spectra, not waveforms: given a target sound, they visualise its harmonic silhouette first and dial the oscillators to match.
Everything you have learned, stacked in one patch: eight harmonics with independent amplitudes and envelopes, a slow LFO for vibrato, a master ADSR for articulation, and a spectrum mirror showing the harmonic profile in real time. This is a complete additive instrument.
The spectrum mirror is a visual check: is the sound you want matching the bars you see? Sculpt the faders until the silhouette reads as balanced, with a clear fundamental and a controlled high end.
Did you know?
The New England Digital Synclavier, used by Michael Jackson and Frank Zappa, was a purely additive synthesizer that cost over $200,000 in 1980. It could control 64 partials per voice with independent envelopes. You are building the same architecture right now for free.

A spectrum city stretches across the 3D scene. Each building's height represents a harmonic's amplitude. Click and drag buildings up or down to reshape the skyline. A waveform river flows through the city center, updating in real time as your harmonic recipe changes - watch the river's shape shift from smooth to jagged as you sculpt.
