Thanks to @Joel Borg for publishing a new video with a KDx overview!
Note that this video pre-dates the introduction of the new note selection interface, so when Joel talks about having to return to the synth to select notes using the keyboard etc., this is no longer the case.
In the video, Joel mentions that he would like to see additional controls in the performance mixer to more closely reflect those in the mixer on the synth, so I have just pushed an update, and now they do!
