The Instruōtanhis a three channel waveshaper, limiter, overdrive, and feedback controller.
Each channel of thetanhtakes a signal input and outputs the hyperbolic tangent function (tanh (x)) for that input signal.
… In more musical terms, tangential distortion is a form of soft clipping which can produce signal amplitude limiting via analogue waveshaping. Driving a hot audio signal into it will add warm overdrive.
Raw waveforms will be subtly shaped; softening or adding harmonic content based on input amplitude.
Understanding what thetanhdoes to a signal, both mathematically and sonically can be hard to explain, but it essentially adds curves to signals.
For many Max/MSP and/or PD users, the [tanh~] object may be familiar and is likely a much used secret weapon in many contexts.
tanh | tæntʃ| noun (mathematics) the hyperbolic tangent of (x); or as a verb… “a’m gonna tan-h that”
4HP Depth: 27mm
+12V: 15mA –12V: 10mA
The tanh has three independent channels for wave shaping.
