15 years ago, I released this video of me playing with a new iPhone app.
That app no longer exists, but I wanted something similar – but I’m getting sick of the app store scene. Lucky for us, technology has advanced in the last 15 years!
Can this be done in a web page now? Indeed it can! Want the app directly on your phone? It’ll do that too!
There are a couple of changes I made to this implementation. Because you can specify exact frequencies in the Web Audio API, I decided to go with a different tuning system, “Just Intonation”. The tuning system we are all used to, “Equal Temperament”, is great for playing in multiple keys – but everything is always a little bit out of tune. Just Intonation only really works in a single key, making it an excellent choice for really beautiful chords and melodies.
It also has a button to save a snapshot of your creation to a MIDI file! :-)
Try it out! (no ads, no cookies, just a thing that makes fun sounds.)
