Just messing around and nothing worth showing, but the web audio API gives all the low level stuff, and then hot module reload from webpack means you can change a function while the music is playing and it updates in real time. Not being bound by a GUI makes it trivial to do things like arpeggiate or automate filters, and then orchestrate that at higher levels

It's easier to break the mould if you're not bound by other people's software, but starts to look awfully sciency if you explore too far : D So it's useful to keep wiping the slate to not be bogged down by previous experiments
