Just a minor niggle.
The track and sound editors allow you to add timeline markers.
This is not the case for the note and curve editors, even though the editor profile allows the addition of a marker region.
Timeline markers in these editors would be introduced, for example, when an articulated sample is triggered through a vst sampler. The playback position within that sample could then be marked along the length of a sustained midi note. That said, I’m not sure how useful it would be. 😕
