You simply drag a midi or realchart out of the plugin into the DAW to give the tempo map so it will sync to the tempo changes:

hopefully the plugin will soon be able to import midi from the DAW to give a tempo map.
The plugin also needs to follow the tempo map of the DAW on playback so tracks already generated at a constant tempo will playback to the DAW tempo map.
