Sorry, I just realised that this tool is kind of useless* at the moment, since live recording in Renoise is broken:

I guess it is best to take this tool offline again for now?
*useless, because the point of the tool is to record slices live, without editing stuff, but due to the bug, the recorded notes are all over the place and stuff needs editing anyway, so it doesn’t really add much over just using Sxx command at the moment…
