Pd (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing. It is the third major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, jMax, etc.



Max/MSP is described as 'Interactive visual programming environment for music, audio, and media' and is a music production app in the audio & music category. There are more than 25 alternatives to Max/MSP for a variety of platforms, including Windows, Mac, Linux, Web-based and Android apps. The best Max/MSP alternative is Pure Data, which is both free and Open Source. Other great apps like Max/MSP are AudioTool, VCV Rack, Vuo and SuperCollider.
