@chaosprint Closing this for now, as I don't really have the time right now to clean things up, and I'd like to put more effort into developing the underlying DSP library that uses this (BoingBoingBoing). I appreciate the time put into explaining how to modify the Glicol codebase. It was a good learning experience for me! |

WIP. See #127.
This PR implements 3 bandlimited oscillator types, using the Polynomial Bandlimited Step algorithm (polyBLEP). DSP is provided using the BoingBoingBoing library. They are available in glicol as
blsaw,blsqu, andbltrifor sawtooth, square, and triangle shapes.Everything seems to work, though the node code may benefit from some refactoring. There's also some issues with the gain of the triangle, but that's a Boing^3 issue that I'll need to look into.
