I second that.
The main reason I bought the TimeFactor was the ability to dial in the tempo precisely, as my drummer uses a metronome. I wanted the delays (which I use A LOT!) to be perfectly in sync with the music.
Unfortunately, when we play our songs, I can hear that the timefactor is slightly off.
I've tried it with the Image Line FL Studio software on my Sony notebook and with my drummer's Roland TD9 metronome. Both results were out of sync.
Very annoying 🙁
