I’m pretty new to the OF community, but I have played with OF for a while.
After playing with ofxImGui and DSP (ofxPDSP), I build a set of classes to build synths and UI to fiddle with them.
I bundled everything in my first addon ofxPDSPTools, I had a lot of fun building it.
And for a long time, I wanted to contribute back to the community.
There it is, if it can be of any use, more info in the README.
