Flash + scsynth

Rate this Message:
Hi, I'm a Actionscript guy and I'm trying to hook up my swf to scsynth. I've established a connection to scsynth by starting it up with:
./scsynth -t 57120 Then I establish a socket connection using as3's binary socket class, but disconnecting is a different story. I can't just close the connection because it causes scsynth to panic, and I get this: ... command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full command FIFO full FAILURE +nL Command not found command FIFO full FAILURE {5 Command not found FAILURE {5 Command not found FAILURE {5 Command not found Broken pipe I was just wondering if anyone has tackled this and could tell me what kind of messages I should be sending for a graceful disconnect, then I will learn more about sending some well formed OSC messages. -- Schell Scivally 600 Santa Rosa Ave. Santa Rosa, CA 95404 efsubenovex@... http://blog.efnx.com _______________________________________________ sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |

If you want to join forces i've setup an assembla space for the library here : http://www.assembla.com/wiki/show/osclib svn is here (read only until you are a project member) http://svn2.assembla.com/svn/osclib/ Im developing this as part of a larger project to make some interesting UI controllers in flash for SC (and Max/MSP, i still find SC quite confusing as im just learning it now) Here's a couple of early demos of the UI stuff im building : http://relivethefuture.com/code/flash/BoxTest.swf http://relivethefuture.com/code/flash/IKNodeTest.swf -- I've written a page on the wiki to explain how FlexBuilder is setup and the various dependencies. http://www.assembla.com/wiki/show/osclib/Development_Setup So if you're interested in working together feel free to drop me a mail off list. btw, there is some basic SC test code in the osclib stuff which connects to the server, reads the server status and can load and create a synth (hard coded to 'sine' at the moment). thanks, Martin _______________________________________________ sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |

so how could this work in practice? would it be possible to compile the
synthdef files beforehand using the language, then somehow get these to load into the plugin, then you would just send the OSC commands by some method - java or something. it would be cool (or maybe even essential) for the plugin to be able to load synthdefs from remote paths, not to mention soundfiles and the like.

I think schell just wanted to get flash communicating directly with SC. Because you can use a 'binary http socket' in flash you can connect it directly to scsynth, whereas before you needed something like flosc to act as the middleman. That opens up a lot of different possibilities depending on what people want to achieve. The flash app doesnt have to run in the browser it can run on the machine like any other app and just be like another SC client. but, there might be a way in the browser to get both the flash plugin and the SC plugin talking to each other, which would be quite interesting. Or, you could have a flash app in the browser talking to a normal scsynth instance (although this would need some extra work to implement the security requirements for the flash player so it can connect to a local socket..) Then there was another idea which i think was hinting at something like this : instead of using the editor part of sclang, make sclang a 'compiler service' which listens on a particular socket to which you can send source code. Then sclang could either send the compiled synthdef back to the originator (i.e. flash) or could send it directly to scsynth. Then the flash application can instantiate synthdefs on the server however it likes. You could imagine having a visual tool much like the standard visual flow graph of PD / Max etc, but you could show code nodes directly in the structure and edit them 'live' (which i guess is similar in some ways to the code module inside synthmaker) of course you could build synthdefs directly in flash and send them straight to scsynth, but if the sc language is there (and its a very well thought out way of managing the server then why not take advantage of that), just treat it as another means of representation. :) martin. _______________________________________________ sc-users mailing list sc-users@... http://lists.create.ucsb.edu/mailman/listinfo/sc-users |
