These would make possible my request for goto prev/next marker possible via scripting, although as useful shortcuts I think they should be native.
More than that there are a few tools designed to give control of Renoise as much as possible via MIDI devices, such as the FaderPort. So far it seems that editing samples with this is a little clunky as you can’t watch the screen and see what you are doing as far as I can tell.
Possibility to script and then midi map zooming, scrolling and selecting (same as right-click/drag with mouse) of the sample editor with API functions I think could be of some use.
