athrú

Instruō's analogue wavefolder in 4 HP, from the West Coast timbre circuit: a fader folds the input from near silence to dense harmonics, with an exponential VCA on its CV. A symmetry bias, a DC offset or a second signal summed before the folder, reshapes its overtones; a strike input opens it for a moment, an analogue drive adds soft distortion.

Key features

• Wavefolding from a fader, its CV through an exponential VCA with an attenuverter
• Symmetry bias: an offset, or a second signal summed before the folder
• Strike input, its decay set on the back
• Analogue drive
