Instruō tanh[3]: three-channel analog waveshaping

The Instruō tanh[3] is a compact 4HP analog module designed to apply hyperbolic tangent waveshaping (tanh(x)) to audio and CV signals. It offers three independent channels, ideal for shaping dynamics, saturating signals, or creating interesting soft distortion effects.

Soft clipping and creative feedback for warm, dynamic sounds

The tanh[3] is not just a waveshaper: it can be used as a limiter, overdrive and feedback controller. In musical terms, this form of distortion adds soft curves to signals, naturally limiting their amplitude and enriching them with warm harmonics. Perfect for giving character to raw waveforms or controlling overly energetic signals.

Perfect for experienced users and experimenters

Users familiar with digital environments such as Max/MSP or Pure Data will recognize the equivalent of the module in the famous [tanh~] object. The tanh[3] brings that functionality to the analog domain, offering instant control and a unique musical response.
