Your point about theremin is well taken @vanakaru, but I am talking about it in the theory section, where I also present a show I did with the theremin, which was, besides sound, used as a proximity sensor -- so I want to show theremin itself, and use it the way I did in the show.

About the real theremin: it may be rather interesting to use theremins cap sensor(antenna) to control something in the computer. But then you need Arduino(or similar) to digitize the sensor. The same would be to utilize theremins 2 ocillators. So it is all analog thus you need to digitize what ever you try. Like taking sound via mic, analyzing frequency, controlling something in Isadora with that data.

I have a moog theremin with CV out. Always wanted to use that output to generate interactive stuff. But you find much more hardware midi to cv, but not the other way round as I would need it. Or better would be: CV to OSC.

Can I use my Arduino One for the CV from the Moog Theremin? Would really be great when I could get nice numbers into Isadora...

vanakaru

@feinsinn

CV seems to stay between 1-5V. Arduino can cope with 5V from analog input. I think it is doable.

crystalhorizon

@vanakaru as I have no idea about Arduino programming, is there something I can look for: website, links, etc...

vanakaru

Take a look at this

Great link, thank you!

Fred

Or if you want a fast cheat plug the theremin into your audio input and use frequency watcher.

crystalhorizon

@Fred so simple and genius!

eight

@Fred: Thanks. That's a great suggestion.

crystalhorizon

@eight can you share the theremin frequency watcher patch if you are going to do it? I cant get it working right

eight

@feinsinn: I have a word from the Theremin Center in Moscow that they will help me set it up, I don't know what kind of equipment they will offer, but if something useful comes out of it, I will let you know. This will happen closer to the end of December.

@eight thank you for keeping us updated

About the DMX controller, I have used both these links and they worked fine with my Macbook Pro.

However I never used Izzy to control DMX (yet)….

Another fun experiment is with Wiimotes and OSCulator… I used one to control a 3D environment.

Also, I second the Epoccam route… it's a great app with little to none delay. Also, they have an app called multicam which gives you the ability to use 4 devices.

@Paulo_Rosa: Thanks, those are great links. Building the usb-dmx converter could be an exercise in itself, should I have more time.

crystalhorizon

I used DMX King with Isadora. Works great and is cheap.

Skulpture

Wiimotes and OSCulator is always fun!

eight

As I am building these exercises, I will be putting the related resources on github.

As of now Exercise 4 is completed.

Update: Exercise 13 is completed.

Working with capacitif sensor to trig sound or video from any object, and make a sampler with several,... With2 cams, video delay or any time effect on real time exchange between people. Even basic split screen with different video delay us fun! But also difference and mirroring says a lot during a show I would be less confident with usb dmx pro since i had problem setting it up ... But i recently drove mac500 automate light with kinect and it s not hard to do if grand ma config is ok for you... Thanks for your sharing it s way interesting topic!
