Hi all! I'm trying to devise a half sine-half square wave. The wave I need must be composed of a crest, a plateau at the center, a trough, a plateau at the center and so forth. I understand this falls under the umbrella of the fourier series, but does anyone have a tip as to how to calculate this practically? More context: my only tool is an LFO with sine/tri/squ/sawL/sawR shaping powers, and I can stack as many as I want. Of course, a trade-off is expected and elegance is desirable. Any help is appreciated!
