I think a reset button in the Shaper contraption would be useful. I envision something where you press the button and all the harmonic weightings get reset to zero.
At the moment you have to drag them all back down so I think this would be a time saver.
Just make a preset with a default shaper. Another note, you can use shift and ctrl to draw either odd or even harmonics in 1 go.
That occured to me after posting...
Thanks for the info, didn't know about the odd and even harmonics feature
