thanks Angelo, the key set marker is mapped to M key, and that is what i have been using, but my reaction time is not as precise as i would like. to me, it is much simpler than scripting, i want to essentially tell Pr to put marker every 2 seconds, which should be a breeze if the feature existed. there is something called extended marker, but that is no help either. are there any plug-ins that makes working with music easier?
