Wavetable Assembler v1.0.3 has been released. View full update details

Wavetable Builder / Generator

Wavetable Assembler is a standalone wavetable construction tool built around two complementary workspaces — a 256-frame Timeline for direct, frame-by-frame sequencing, and a 16-slot KeyFrame lane for spectral morphing between hand-crafted anchor waveforms. Every frame can be drawn by hand, sculpted harmonic-by-harmonic, imported from existing WAV files, or generated from built-in presets.


Two Workspaces, One Wavetable

  1. TimeLine (256 frames)

Sequence up to 256 individual frames directly, with drag-to-reorder, copy/cut/paste across slots, and per-slot WAV import.

Timeline Mode
// Timeline (256 frames)

  1. KeyFrame (16 slots)

Place up to 16 keyframes and let the morphing engine interpolate a full 256-frame wavetable between them automatically.

KeyFrame Mode
// KeyFrame (16 slots)

Two Editors for Every Frame

Waveform (Draw) Tool

Use the drawing tool to draw a single-cycle waveform directly on the canvas. You can also add noise to the waveform and smooth it.

// Draw Tool

Additive Editor

You can edit harmonics and phase up to 1,024 harmonics. This is effective for generating metallic tones and clear sounds.

Spectral Effects & Partial Modifiers

Apply DSP effects and spectral modifiers to a single frame or a whole selection at once.

Spectral Modifiers // 10 Modules

ID: 01Active

Remove Even Partials

Removes every other harmonic for a hollow, clarinet-like tone.


Waveform Effects

Apply a DSP effect to the active frame or an entire multi-select of frames at once, from the side panel.

Waveform Effects // 13 Modules

ID: 01Active

Sync

Phase Distortion: The classic CZ Resonator sound.


Spectral Morphing (KeyFrame Mode)

Each keyframe-to-keyframe transition uses its own morphing algorithm, plus an optional post-morph shaper with an adjustable min/max range, giving fine control over how one waveform evolves into the next across the table.

Morphing Algorithms // 8 Modules

ID: 01Active

Spectral Wander

The tone drifts and wanders naturally as one frame turns into the next.

Optionally layer an extra effect on top of the morph itself — like Sync, Fold, Drive, or Phase Modulation — that fades in and out smoothly across the transition.
