Con-GAS

2004-01-30

Con-GAS is a joint European research program focusing on Gesture Controlled Audio Systems. The main objective is "to significantly contribute to the advancement of the development of different gesture data analysis and capture/actuation aspects connected to the control of digital sound and music processing."

The industry of digital musical instruments and devices is well developed in Europe (particularly so in Italy France Germany and United Kingdom) however devices taken into consideration by this industrial field do not go much farther than keyboards and sliders. Extra-European industries (particularly north- American and Japanese) do reserve deeper attention to different control and gesture schemes for digital sound devices."

Nostalgia?

2004-01-28

Me Øyvind B. Lyse and a friend of his were having a beer the other night and started discussing why we keep coming back to music we listened to as teenagers. I guess I spent a lot of time and energy trying to understand and define myself at that time and music was an important mean for doing that.

Coming together

2004-01-24

The installation me Jana and Jørgen collaborate on is coming together now. It is going to be toured at schools in the Hedmark region in March. Jana will visit a school a day and set up the installation in the gym hall. The installation is made up from 20 sensor doormats. As the kids move around they will trigger sounds played back from a four loudspeaker setup. Max/MSP is used to control sound in real time.

The doormat sensors are simple on/off switches. Most of the time we’ll use them for triggering playback of sound files but one of the modes is based on syncronized playback of a 16 track rytmic loop the doormates controlling which tracks are to be muted at any time. In addition we’re creating a non-interactive background layer giving a sonic fundament that sensor-controlled sounds can act against.

Me and Jørgen tried different combinations of interactive sounds and background stratas yesterday. It’s the most effective demonstration I’ve experienced to this day of how much stronger the total impact becomes when there’s several contrasting musical layers present at the same time. Shepard tones are used for some of the background layers as well as the interactive part. When combining rising shepard tones for background and interaction the interaction was more or less masked by the background. Substituting the interactive sounds for falling shepard tones made it all come out so much clearer. Increasing the difference between the background and interactive layers further improved the overall impact even more.

Still I’d like to create one more background layer that has a more processed and distant quality to add depth to the soundscape. Also I’d like to see stronger fluxtuations in time than at present so that the sounds cape is drifting and turning on itself to a stronger degree. I’ll see what I can do of further devellopment based on the sounds that are already present. I have some ideas of what to do based on granulation delays and an interesting MSP filter that I haven’t tried using before: teeth~. teeth~ is a comb filter with feedforward and feedback delay control. It’s at the core of the Pluggo FX “Generic Effect” and is used for creating a wide range of effects: delays vibrato chorus flange comb filters etc.

I don’t think it’s a good idea to introduce more material now rather we should try to find different ways of combining and develop what’s there already.

Monday we’re going to run tests with kids at a school in Oslo.

Årsrapport

2004-01-22

Most of the day has been spent writing about finances and organization for the BEK Annual Report. If in danger of feeling we actually did a good job it’s nice to have NN around to put things straight.

I was posting a message to several international mailing lists yesterday to announce that BEK survived the recent financial crises. I won’t be surprised if she starts mouning about lawsuits and contact information for members of the board at BEK again. If she googles around a bit she’ll be in for a surprise…

My office...

2004-01-22

…looks as if it’s a testing and demonstration room for doormat sensors at the moment. I’m jumping around to hear all kind of weird sounds that Jørgen Træen has been making up. With this kind of sensors we should have some dogs barking radios turning themselves on and off and elderly people speaking the same phrases over and over again. Finally the stuff I was struggling with some days ago is working. Me and Jørgen will spend a few hours together tomorrow and the coming Monday we’ll run tests with school kids in Oslo.
