I've upgraded to the latest version for the first time in a year or so and now the audio analyser seems to crash 2 or 3 times a night leaving the scanners motionless.
Then when you close and re-open the bpm window it removes the bpm setting from all the scenes that have it and you have to right click everything to select bpm on step again.
We'll fix the DVC2 bug in the next version with the pairings being lost, however we'll need more information on the audio analysis crash to be able to fix this.
