Tested with my own music production and the first similar result was quite impressive!

I did something similar to it for my own use. Using natural language it make sql queries to your .csv, xlsx (soon I'll add features so you can connect to databases). but it is not mature enough to sell as a service. Feel free to reach me info [at] rafaelmelhem.com if you want and I send a demo :)
