Control Max patch with HTML 5 web interface

Mar 19 2012 | 5:09 pm

I’d like to make a web interface that allows users to change parameters of a generative max patch as the output streams. It seems like HTML 5 will simplify this kind of thing– here’s a project that lets you control a modular synth remotely via HTML 5:

Never having used HTML 5 I’m not sure what form the messages from the web interface to Max would need to take. Any pointers to learning this would be appreciated!

you could, for example, play or loop pieces of audio or midi on the site in order to have something to output (from the browser to a hardware out) at the client side.

or eventually you can work with protocol handlers … with javascript it should be possible for
a site to add a protocol handler to the browser on the fly …

thanks Roman,
What I’d like to figure out is how to replace the hardware synth in the linked project ( with a Max patch running on my machine. So you would have a web interface that sends messages to the max patch, which streams the audio and video back to the net.
The choice of HTML 5 for the above project makes me wonder whether there are special/new features of it that would make this easier to implement.

Hi everyone,
I dig this up, cause I too am wondering to what extent it’s possible to create a web browser based interface, that sends messages to a max patch running on the same machine. I’m not trying to access the patch through a distant network, it would be too slow anyway for what I intend to do. Is there anyway to send udp messages this way ?

Thanks in advance !

Have a look at this – (link in the description).

It’s possible with node.js – you communicate to max through OSC – in the case of vtouch it is communicating to python (LIVEOSC), but the process is much the same.

I doubt this will work on a mobile app though (phonegap etc)

here’s one solution:

Sweet !
Thanks to both of you, I’ll check on those methods !
