The 4th Order Non-linear Map basic Graph Building block is useful for adding second, third, or fourth order harmonics, (among other uses) Brian has created a stand-alone app to help visualize the transfer function of this powerful graph block. Helping to choose the correct values (-4 to +4) to create the appropriate curve response.
For anyone interested in getting a view of what sort of transfer functions can be created with the MIO NL(4) Map, you’re welcome to download the program Brian put together to visualize this.
Nonlinear-Map
It’s a Universal Mac application for Intel and PowerPC, and you can drag-install it anywhere you please.
I might eventually get around to implementing the Symmetric version, as well as adding a checkbox to flip between the normal version and the [dB] scaled version of the parameters.
