I'm sure that it has not escaped this community that rekordbox 7 users are pushed to share their analysis data with AlphaTheta and upload it to their cloud. To anyone familiar with how AI tools are implemented (mostly based on neural-networks) this likely means that they'll use this data to train their existing and new AI tools. It's only natural to think that one important application will be to completely automate beatgridding tracks, including ones with dynamic tempo.
I hope that NI takes note and will be ready to compete on this very useful feature that, I'm sure, will attract many DJs.
