Create a synth editor #17
Description
I think it would be really cool to be able to create your own synths from within the app. This means it is not necessary to have a bunch of soundfonts for different instruments, as the instruments can be synthesized live using the web audio api. The web audio api is very versatile and it should be possible to generate a wide variety of sounds using different oscillators and filters.
https://github.com/gre/zound-live looks very promising, and since it is licensed under the GPL, we can make use of some of their code.
