I would like to know if there exists a list/ documentation of all the tools in Pd?

I am a beginner and I want to create a tuning-software with some pretty new features. My vision of just intonation...!

I am a classical Tenor and would like to open some doors for the classical music since the evolution of harmony is completely stuck.
So far Pd seems to me a very powerfull instrument, but I need an overview of the objects.

There is no such comprehensive and definitive list because Pd is a moving target in constant development. There are many partial lists, tutorials, guides and directories of externals/abstractions dotted around the web. Best of all is Pds own very fine Help system having pages of well written but concise usage examples.

You might also care to join pd-list where you will make many friends who are composers, musicians
and sound programmers.

There have been several discussions of microtonal and alternative tuning. A quick search of the archives should lead you in the right direction.

best wishes
