técnicos.Parte 10: Interactivity with sound.

Hello! Here again we are experiencing!. By time I had wanted to get to research on how to handle our "soundtrack" directly with the movement M. Angeles on stage. From the outset we decided to leave that part aside for a matter of time and especially because David Crespo (Balago) was composing the music and we had not tested it. Now we already have and take the opportunity to tell you that David's work has contributed !!!... I love wealth and textures that make the single most exciting yet, with its own personality.

From this point and we have been doing tests with Victor Zambrano will miss start this point of interactivity that I said before the sound. Actually so far it does the DJ was playing music since destrozábamos issues based on the work of MA, but she was not able to change the music with his own interaction. And here we are, as you can see in the video below.

As you have seen is a home video of an example and show our software to puncture live VirtualDJ is the . This software is very simple and effective for puncturing the issues but has a very great limitations, which require hard work. The reason for using this software is that Mario and I know him really well but the thing is complicated when you can see its flaws, and their support is lousy, their progress in their versions are very limited and just see its user community gives a little slump, but anyway, in the end I think we will.

Here is a little more detailed explanation:

Sequence of events to make it work on the second computer based on the movements detected by the camera first:

1 / As we know, we Processing to generate and detect visual motion and make in-puts to them. Well, now we need to make our programming send specific signals of what we want to modify the sound base. We will use the communications protocol OSC and library OscP5 to P5 (Processing).

2 / will issue these commands by creating a network wirelessly from computer to computer, this Mac is pretty simple. This will locate the ip port and tell you to have direct communication with Osculator , a wonderful software that converts any signal Osc to almost anything. A soft it is cheap (14 €) and very careful design and function.

3 / convert this signal to Midi Osculator and assign a channel (usually one).

4 / As VirtualDJ not virtualized by a cop midi port created on the machine, we need to do this with another program Midikeys style (Free), VirtualYoke in Windows. With Leopard you will have no problem, simply download the page if you have Tiger, you have to use an older version available in a mirror that goes as you type Google version.

5 / Well, we go to the Midi Mac utility (Utilities in the Applications folder) and activate the IAC Driver object for this to become a port if you have communication with VirtualDJ. After we will Midikeys and select the input port and output Osculator the IAC Driver. If we give some key catches VDJ see the signal.

6 / assign channels and functions in the Midi Mapper brings VDJ version 6.1 (what bad thing in my life have I seen something like that), but eventually gets set.

Well, I gave you the clues to do this when you are interested in doing it this way, you see there to mount a good and spend some time, the machines also squeeze the end is fun. ;)

Until the next post!
