How do we regionize a track? convert_to_region intro mark1 mark2 convert_to_region chorus mark2 mark3 convert_to_region verse1 mark3 mark4 convert_to_regions mark1 intro mark2 chorus mark3 verse1 mark4 Consider we may want a short overlap (0.01 seconds?) for a cross fade. Do we need to clone/rename the marks for each region, so that each can be adjusted? Or do we keep the marks, and just adjust with shift? For each region, we can clone the effects. Having a track for each region means that each region can have it own effects. We've previously broached the question of how to present regions to the user. One possibility is to manually select a region, another is to let the playback head position determine the region. Envisualizing, Joel -- Joel Roth
