I could fantasize even further. A PureData plug-in could kickstart a VCVRack type effort - an open source library of interconnected audio processing modules.
The fact that it's paid might be a turn off for some, but I've found it to be really useful, and it works really well inside of Ableton. Can't speak for other DAWs but having been using it for the past 6 months or so, it's been fantastic.
Does anyone know of good resources for folks who want to develop their own modules for VCV rack?
In terms of the dev resources:
1. Here is a basic official tutorial: https://vcvrack.com/manual/PluginDevelopmentTutorial
2. A pretty good video tutorial: https://www.youtube.com/watch?v=d670AFZKGnw
M4L and PD allow you to open the patch ("patch" as in MaxMSP patch, not a Eurorack patch) and edit its source code. Which is a completely different level of sound manipulation and synthesis.
You can also run PD as a plugin inside Rack to get "the best of both worlds".
