Today I needed to make a sample that would play a portion of a sample instead of playing the whole sample, from a nexus ui waveshape element. There are three problems that disallowed this:

OpenSCAD is a freeware that you can use to make 3D models from lines of code. It is good for parametric design, but as you may guess, it is not so intuitive to use. As far as I know, it neither is good with organic shapes (A curious fact: the Utah teapot) but rather works well with orthogonal shapes. I have dared for the first time to use OpenSCAD. I previously did some tiny attempts, with no major success. The code very easily became clumsy. The notes that I will present can help an incoming user to take a comfortable approach into it:


I took advantage of how there are many youtube videos that are intended to be part of songs, such as jam backtracks. In this experiment, I put youtube to jam with youtube by matching videos from their BPM and scale. Visit it: djroboto. Watch the source at GitHub.
