13. Waveshaping in Pure Data

[@jonkruth4157]

wow you are the best pure data teacher ever

[@andygrichting]

Wow, thanks, now I finally understand what this square with the diagonal line actually means, seen so many times, used so many times. Thanks a lot, that's amazing :)

[@WARDISWARD]

LOL , it's an X-Y axis where the x input positio equals the Y position iow a linear , that's high school material

[@marcocatani2031]

great video, thank you

[@denizatalay]

This one was interesting!

[@WARDISWARD]

I never use the $0 variable when declaring the tabread , why do you use it ?

[@QCGInteractiveMusic]

$0 appends a unique instance number to the table so that if several arrays with the same name are open (e.g. across multiple patches) Pd uses the appropriate one(s).

Amazing series! But I can't understand why we add 1 then multiply by 50. Can someone explain please?

[@patrickmanion8736]

We want to map the min/max osc~ values onto the x axis of the array. The oscillator volume ranges over [-1, 1] inclusive. If we add +1 to every number the volume will now range over [0, 2] inclusive. If we multiply this by 50 the numbers will range over [0, 100] which is the input range of the table (x indices range from 0 to 100). This allows us to read the out the y values of the graph. Hope this helps!

At 4:33 you choose the array X to be 200, but at 7:40 you only scale up to 100. Did you mean to scale up to 200?

[@jemery2016]

At 5:46 he changes from original 200 to 100 to be consistent with resizing.
