I think this has been discussed before, and one thing I don't quite like about rendering a selection is the following thought: Should all channels be rendered, or only the selected ones? I think most of the time you would want to render all channels, and having to select them all would just make this action more complex. If it's only the selected channels, what happens to partially selected channels? Should they be treated like a full selection? Should only channels where at the note column is selected be rendered? etc...

Note: This doesn't mean that I'm against the feature, in fact I think it's quite useful, however the different ways of exposing it to the user first need to be evaluated.

I ask for option render orange zone in picture.

Hi again, I dont know it's easy or not, but if you can add option "Render selection to sample" after "Lock playback to selection" in pattern menu, it would be amazing.
