True, but then, that’s pretty standard practice in any DAW. You have Audio Events that refer to a single file on disk, and you can have many Events that refer to the same file, so that any change to that file is reflected in all clips/events. Or, you can make new file copies for different Events so they are now unique. Nothing new here. Pretty standard. Audition has been doing this since at least 2012.
Therein lies one of the problems. Why not? Cubase has been around a LONG time. My first impressions is that Cubase is really good at importing things that it creates.
“Events” in Reaper are called Items, and each Item has a Source (in this case a WAV file on disk). If I pull up the Source Properties for this Item, it tells me that there are 103 Cues in the WAV file Metadata (along with a whole bunch of other information). So, basically, Reaper just places cue marker indicators, along with the correct names, over the waveform in the Item where they are supposed to be, based on Time. They move with the waveform if I Slip the contents within the Item. They aren’t ‘transferred’ to the Item, but are a property of the Source itself, and are shown for reference. There is a menu option to “Import Media Cues from Items as Project Markers”, which creates Project Markers from the source metadata that align with the CURRENT position of the Item when you do the import. If you move the Item, the Item markers move with the Item, but Project Markers do not. They are now fixed to the project timeline. Think of it like clip automation vs track automation. No difference.
Item markers are ignored. Only project makers are used in mixdown.
As I mentioned earlier, for Audio in particular, an Event in Reaper is called an Item. That’s the container on a track that holds the audio information. You can do things to it, like automation, or gain, pan, reverse, apply effects, etc. All of this is non-destructive, as usual. The Item references a Source file on disk. I don’t know about Audio Parts, but basically, we have Tracks > Items > Source File on Disk. I’m pretty sure that’s the same for MIDI as well.
Videos? There are literally WEEKS worth of quality videos on every aspect of REAPER in excruciating detail on the Reaper website by a guy named Kenny Gioia.
