Make a plug-in that detects key & key changes, bpm & bpm changes, time signature & time signature changes of samples/songs via listening- (the plug-in would show live information or any changes on the plug-in user-face) Or drag n drop, then insert sample/song information directly into the playlist. BPM and key changes will be shown in separate automation clips if any; FL studio will send them to playlist as automation clip(s). Time signature changes will be sent to playlist in the playlist marker section changing the time signatures for you automatically.
you could add this to edison or make a new plugin and call it 'huddison' and focus on these features great for any artist, producers, DJs and listeners/music lovers. This would help all FL studio users stay on beat and possibility in key more often.
