Another web-based DJing app. It does not look pretty, but it uses a lot of capabilities of the new-and-shiny WebMidi and WebAudio APIs. It is a showcase, if you will.
supersaw is a minimal DJing application in the browser, supporting such things as speed, pitch, volume, a 3-band-equalizer, a couple of basic effects, visualizing the wave forms and, the coolest feature, talking to an external MIDI device (e.g. a controller).
Also a slightly new feature: we created a new html input element based on the range that
inherits its behaviour from the range element.
The midi features were tested with an Behringer CMD MM-1. It should understand all midi devices, but returning fancy instructions (e.g. if your midi device supports color change on pressing a button) may fail.
For best performance and experience, please use Google Chrome (we're really sorry). Namely, the Firefox audio tag does not support speed adjustment natively, which sucks for us. Also it does not implement the WebMIDI API just yet, which sucks even harder for us.
We advise you to go to the website to play with the thingie, but
if you want to run a local copy (or the server is down), clone the repo, run npm install
and grunt (if you want non-minified js) or grunt prod (if you want slightly speedier
minified js) and you're good to go. The server should live in localhost:8000. Enjoy!
Note: For using a controller, you have to enable the MIDI API manually for now. It will be enabled by default in the next release of Chrome. Here is a concise answer on how to enable it yourself.
the html files can be found in html. the only file that might be interesting to you
is the knob.html file, where the custom html element is described.
JS code is dived into src, where the main code lies that sets everything up, and
lib, where effects and widgets can be found (each in their own file).
We refrained from using any framework except from those builtin in the browser (and grunt for building), so it might seem a bit backwards, but we saw that as a challenge set for ourselves. We do not apologize for any inconveniences this might cause for you.
