beat sequencer

I just made this little beat sequencer, its a simple prototype for a bigger project.
Its basically a grid on which you can place colored squares that the webcam recognizes as a certain beat on that channel of the grid.
It runs super smooth thanks to sonia!.
In the clip you see me placing squares which it then recognizes as a beat, in the end I crank up the speed of the loop a little. the clip doesnt run too well cause it couldnt handle the app and the screencapture software running at the same time

Wow, I'm so happy to see Sonia being put to such wonderful use!
The new release of Sonia is shaping up. I think you'll find some of the new features very helpful.
Furthermore, Steve Helquist is compiling a great reference, and we'll be using Casey's processing-admin tools to have it available real soon.

cool,really looking forward to it.
future features of this thing include a much 16 measure grid with around 8 channels, cubes with a different colors on each side so you can switch samples on the channels, and a custom built box/carrying case which you can just plugin.
I'll put up more as it progesses.

Hi,
I'm trying to do something very similar (processing webcam input and outputing sound from it) but the moment I create a code folder (containing the JSyn Classes and dll and Sonia) processing gives me this error:
java.lang.UnsatisfiedLinkError: no QTJava in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1403)
at java.lang.Runtime.loadLibrary0(Runtime.java:788 )
at java.lang.System.loadLibrary(System.java:832)
at quicktime.jdirect.JDirectLinker$1.run(JDirectLinker.java:266)
at java.security.AccessController.doPrivileged(Native Method)
Even in a working webcam example (without trying to do any sound stuff) if I add the 'code' folder gives the error.
Any help would be highly appreciated.
Thanks

Hello Eki,
There's a strange bug in procesing-68 which usualy shows up on windows xp (and particularly on non-english versions). This bug does not let you work with the code directory at all. Can you please let me know more about your operating system? Perhaps you are also experiencing this bug.
this will most likely be fixed in the upcoming release (69).

Thanks for answering Amit & fry
Yes, it looks like that's the bug as I'm using procesing-68 on windows xp (english version)
I'm going to try fry suggested workaround and I'll post results
Thanks again

Hi,
Tried the workaround and I get this error now:
quicktime.std.StdQTException[QTJava:6.1.0g1],-9405=couldntGetRequiredComponent,QT.vers:6508000
at quicktime.std.StdQTException.checkError(StdQTException.java:38 )
at quicktime.std.sg.SGChannel.allocate(SGChannel.java:65)
at quicktime.std.sg.SGChannel.<init>(SGChannel.java:58 )
at quicktime.std.sg.VisualChannel.<init>(VisualChannel.java:44)
at quicktime.std.sg.SGVideoChannel.<init>(SGVideoChannel.java:49)
I'm not sure of what I'm talking about but I think there's a version conflict as I've checked the versions and the QTJava.DLL is version 6.1.0.0 and the
QTJavaNative.dll is version 6.5.0.48 and I read somewhere in this forum about QuickTime not updating some of the files when upgrading.
I guess I should look for answers in apple's site. I'll post outcome.
cheers

Hi again,
I've uninstalled QuickTime, installed version 6.0 (QTJava included) and upgraded to 6.5 and everything seems to work.
Thanks a lot mates.
