One thing I'd love to see in a DAW someday is houdini-like functionality. It'd be cool if there was this node-based environment that went a step further than just generating sound and could generate midi clips, automation clips, etc. and have it integrated into the DAW. Like you could see what was generated in the arrangement view.
The sequencer I'm working on, https://ossia.io, has a plug-in API which allows that. But no interesting "meta-creation" plug-ins so far for it ^^' at some point I'd like to provide primitive composition-like tools like some of the OpenMusic objects for instance, and there has been work towards e.g. segmenting a sound file with audio improvisation algorithms by an intern.
