Is it possible to create a Transistor/Valve-Response-curve in Max ? Something like the x/y Display in izotope Trash2? (see screenshot)

I´m really trying for a long time, but don´t not really understand what's the difference between the response curve and a waveshaper (or rather the multislider/waveform~ objects)?

a "valve response curve" is probably first in line simply its frequency response curve, i.e. you could reproduce that with a basic FFT equalizer.

waveshaping for the distortion, or the velocity or interpolation of the gain changes are in other dimensions.

if you want to vaguely model the behavior of a tube, you could combine these two dimensions as follows:

1. make a copy of the signal and apply a bit of gain reduction to the sub basses and the very high frequencies (or raise the mid) with any kind of filter or eq you wish.

2. distort the eq´d signal with a waveshaper (or with the max forum-common-sense-method of [*~ pi] – [tanh~] – [/~ pi])

3. now sum it with the original and have a version of the input with the mid frequency range beeing a bit more distorted than the hi and lo.

Thanks you very much. It helped me a lot


 to acknowledge the answer of your question. Creating a transistor / valve responsive curve is not easy to do but yes @Roman Thilenius posted a good answers for those people who have no idea about it.
