By automate, do you mean, you can draw in tempo changes? A lot of DAW’s seem to offer that and few allow you to slave the DAW. I’m hoping for one that let’s you slave the DAW and while its a slave, have it draw in the tempo it detects. So for instance, if I program tempo changes into the master, not only will the DAW follow those tempo changes but it will also record those tempo changes into the ‘master tempo track’ or whatever.
