The Pd4Max library contains some of the most essential Pure Data (PD) objects for signal processing into the Max/MSP environment. It enables accurate implementations of the patches/examples from M.Puckette's "Theory and Techniques of Electronic Music" (https://github.com/georgeNikmus/The-Theory-and-Technique-of-Electronic-Music-Max-Patches), and A.Farnell's "Designing Sound" (https://github.com/georgeNikmus/Designing-Sound-Max-Patches). With this library, most Pure Data projects can be ported to Max/MSP with some minor modifications. The binaries are now available for Windows and macOS! Contributions and corrections are welcome!
Note: The pdquad~ object corresponds to the biquad~ PD object. I changed the name to avoid conflicts, as Max/MSP already includes a biquad~ object, which is slighlty different than the biquad~ PD object.
