Thanks for taking a look! Let me know if you have any issues with it, it's still in a nascent stage and has a lot of room to grow especially in the Guitar to MIDI detection. If you don't have a midi controller you can use your keyboard as well !

Would be nice to have it be realtime no, is this something you are looking to have? Do sign up on the cloud waitlist so I can get in touch wrt progression on the chord detection work.
