I've been working on a CLAP plugin for DAWs that sandboxes a scsynth instance and lets you edit and execute supercollider in real time directly on a track.
Correction for the title: "... edit and execute supercollider code in real time"
SoundIn.ar directly comes from the track, Out.ar goes directly out to that same track. Perfect for creating track effects.
You can also create instrument tracks very easily, with MIDI and MPE support.
