Hey everyone, thought some people here might find this useful -- I made a website that generates random "standards" and chord progression forms for you to practice improvising on and lets you import it directly into iRealPro.

Please let me know if you find it useful, or especially if have any feedback on how to improve it! It's my first web app -- I made it mostly for my own practicing but figured some other people might get some benefit from it, too.
