Hitpoint-based Audio Quantization apply on different Tracks?

Hi,

Yes, you can do this. Put all of the tracks to one folder and enable Group editing of the folder. Then set the threshold of the Hotpoint detection on one of the tracks. Then select all tracks in the folder and open Quantize panel [F6]. Now you can Quantize it as a group.

I believe there are plenty of video tutorials on YouTube, if you search for Drum Quantize.
