I’m thinking about a tool that is connecting Renoise pattern data to Excel, meaning that you could edit your pattern data in Excel with bi-directional (near real-time) updating. It might not be a good idea to use Excel as a substitute for the pattern editor, but it could surely bring a lot of fun possibilities when it comes to pasting parameters, manipulating values or generating values by formulas.
I’ve been trying to investigate if this is even possible. It might have been if the LuaCOM library was included in the Renoise API - http://www.tecgraf.puc-rio.br/~rcerq/luacom/pub/1.3/luacom-htmldoc/luacom.html . Maybe there are other approaches that could be used to realize this?
