  • Page 3 Description The Instruō tanh[3] is a three channel waveshaper, limiter, overdrive, and feedback controller. Each channel of the tanh[3] takes 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.
  • Page 4: Installation

    Installation 1. Confirm that the Eurorack synthesizer system is powered off. 2. Locate 4 HP of space in your Eurorack synthesizer case. 3. Connect the 10 pin side of the IDC power cable to the 2x5 pin header on the back of the module, confirming that the red stripe on the power cable is connected to -12V.

  • Page 6 There are three channels of identical tanh[3] circuits. Input: Signal input. • DC coupled input for audio or control voltage signals. Output: Signal output. • DC coupled output for audio or control voltage signals. Level: Input signal level. • Moving the knob clockwise will increase the amount of waveshaping.
  • Page 7: Patch Examples

    Patch Examples Waveshaping: • Patching a triangle waveform through tanh[3] will allow for some interesting waveshape control. • When the Level knob is fully anticlockwise, the resulting signal will be a slightly attenuated triangle wave. • As the Level is increased, the corners will soften and the waveform will shape into a sine waveform.
  • Page 8 Limiter/Distortion: • Patching complex audio signals through tanh[3] will result in signal boosting, limiting, and distortion. • Sounds such as kick drums, bass patches, and chordal pads work particularly well. • The effect is sonically similar to compression but achieved through waveshaping as opposed to gain reduction.
  • Page 9 Feedback Control: • tanh[3] can be inserted in a feedback path to reign in runaway feedback. • This concept works in all feedback contexts, including delay loops, reverbs, filters, and microphones. • In this context, it functions as a limiter on feedback amplitude. •...
