Extended Technique Generator

CROAK

verb (informal): to die. noun: a deep, hoarse sound, like that of a frog or crow.

CROAK is a dual generator that channels the raw, unpredictable energy of extended acoustic techniques.

From smooth to shattered, from digital rust to organic heaving, CROAK produces textures that feel more real than your brain believes could come from a Eurorack module.
Two voices entwine to form the sound of reality on the verge of breaking apart—then disappear into spaces you might not return from.

Inspired by the playable autonomy of standalone synths like Rob Hordijk’s Benjolin and Hikari’s Duos, and the visceral language of free improvisers like Steve Lacy, Colin Stetson, Evan Parker, and Peter Brötzmann — CROAK merges instrument and machine, chaos and control.

“It needs to be played!” – Hainbach
“I’d swear it was mic’d, not patched!” – audience member
