Here is a tool to generate chord progressions out of some random chords.
It is a way to kick-start a new track when out of ideas. Or… That was the idea when creating it 
Since it’s my first tool, and also my first encounter with LUA, it probably has more bugs than lines of code. It do work on my computer though, of course.
It writes to the current pattern. Screenshot of gui below:
More info on the tool page.
Just joined and have been using renoise for a while but I didn’t even know that it had an available API and that it can be scripted for plugins with LUA. This is great news! Going to check your tool out. Looking good, keep up the good work!
