A / THE SOUND'S JOURNEY

An extreme and flexible signal path for extreme and flexible sounds.

Three voices meet before two movable filters. Noise enters between those filters, so their order changes what shapes the texture.

Comb first gives the voices a resonant body; Character then shapes that body and the Noise inserted between them.

ON THE ACTUAL PANELMove the filters to change which sound takes the final shape. Put the resonant comb first to ring the struck voices before Noise enters; reverse them and the comb also catches the added texture. The chosen type and settings move with each filter.

B / SEVEN WAYS TO SHAPE A STRIKE

Choose a body, choose a character, and change their order. Each type remembers its own settings.

I / CORE

Two bodies
in conversation.

Two independently tuned resonators turn a short excitation into a ringing body. Coupling sets their interaction; damping shortens the ring.

II / SPECTRAL

Metal from
mathematics.

Two FM pairs forge sidebands from clean tone to clang.

III / STRATA

Eight partials.
One afterglow.

Eight sines stretch, scatter, and sculpt a ringing strike.

IV / NOISE

Hear the grain
of the world.

Seven noise types blend into the signal between the two filters, with their own decay. The second filter shapes the combined sound.
