Cathodes, LED's etc

well the only thing is, if you look at reactable, it can have symbols for drum loops and such so you can make a beat, if you can do that too it would be good, I wouldnt say it failed miserably, you should be proud you did something that others wouldn't have had a go at.

These are the objects that I was moving around on the surface. So they do have symbols on them denoting what each of them do, it would be impossible to use if they didn't.

It is possible to use only loops and have them sync to each other, but I chose not to do that, for the primary reason that a friend of mine was building 2 of them and triggering sounds with them. So I wanted mine to be different to his. It was also easier to have it generate what could be described as primatives or the basic building blocks of electronic sound. In the future I'm looking at incorporating a display/visual feedback, as well as interation based on proximity and a sync'd audio system. But for 11 weeks what I've got isn't bad. Now to edit my 5000 word paper on it.

5000 word...interesting!

I understand some of the symbols but whats the 2nd 3rd and 4th vertical lines of symbols mean?

another cool idea would be to invent a touch screen interactive which you can DRAW with your fingers the symbols and such on your display, once drawn you can then make them a permanent movable object on the screen, move them around, adjust properties by sizings or attaching other symbols....man that would look cool.

Ok, I find that quite interesting, but I kind of knew that would be the case. When I did the final sound installation on teh night of the performance I had to cut back which symbols I let people use. 1A and 1B are 2 parts of a granular synthesizer, and the same with 2A and 2B.

I wanted to create the device so that anyone could use it straight away, but also make it so tha someone who wants to put more time into learning it has some harder symbols to learn to use.

The middle top is drums (obviously), and the 3 below it are what I call 6-notes. These symbols have the rotation split into 6 different areas to give something tonal for the player to use, rather than just continous variables.

The 4th column is 3 sample symbols. So you put them on the screen and they playback a sample that has been pre-chosen. At the moment, the first 1 is a timing symbol so that I knew how long the performance had gone for, and the other 2 are just random samples. Named 16 and 17 so that any sample that is named 16.wav or 17.wav can be used. The reason for using 16 and 17 is that they are the ID's of the symbols. The bottom one in that column is a awtooth wave.

Top right is a sqaure wave, but instead of going from low to high and then jumping back to the low pitch when crossing the 0/360 degrees, it has the same frequency at the 0/360 degrees and another pitch at 180 degrees.

And yes that would be awesome. The guys that made the original reactable have it so that you can draw what waveform you want with your finger and change the generator to that sound. Creating the gesture library would be the tricky part.

Here is my installations and performance with the Reactable.

I've also uploaded a software version which can be found here. You'll also need to download Pure Data which is the program that I've used to make sound. It can be found here.
