8 voice generative sound synthesizer

Glintbox

Randomly triggered voices produce shifting notes, chords, and textures. Shape the relationship between the voices with shift and spread, then push the result through distortion, reverb, and musical scale modes.

Eight independent voices

Each voice owns its own pitch. The synth keeps moving because the voices are triggered randomly instead of being sequenced in a fixed grid.

Shift, spread, scale

Shift and spread tune the relationships between voices, while mode selects the musical scale. It can drift into soft tonal clusters or become noisy and abstract.

Built-in color

Distortion and reverb give the instrument enough pressure and space to stand alone, from brittle fragments to mellow, slow-moving tones.

How to use

Controls

Glintbox has eight voices. The voices are triggered by an internal random clock. Each trigger starts one voice envelope. Turn a knob clockwise to increase its value.

Start with Level around the middle, Density low, Rise low, and Fall around the middle. Then adjust Mode, Shift, and Spread for pitch behavior.

Rise Attack time for each triggered voice. Low values start immediately. Higher values fade in more slowly.
Fall Decay time for each voice. Low values make short hits. Higher values make longer tones and more overlap.
Density How often new voice triggers happen. Low values are sparse. Higher values trigger more often.
Mode Selects one of five pitch modes. The mode changes the scale or note set used by the voices.
Sparkle Distortion amount. Higher values add more saturation and fade in more of the distorted signal.
Shift Moves the pitch set. Use it to transpose or offset the relationship between the voices.
Flutter Adds pitch modulation. Higher values make the voices move around more.
Level Output volume.
Spread Controls the distance between voice pitches. Low values keep pitches closer together. Higher values spread them further apart.
Space Reverb amount. Higher values make the output wetter and larger.
