I am working on a Sound Installation for a special Education School. The Installation is going to be located in the Snoezel Room (a room with a soothing and stimulating environment). So the basic Idea is, that you can press a button (or another input device like IR ... still working on this) and then a "Star" (Led lights at the ceiling) turns on and a corresponding sound is heard. The light is supposed to fade together with the sound. To be able to achieve this I want tu use a Bela that runs a PD Patch and controls the LEDs. So right now I am still working on the basic Patch, that has to be PD Vanilla (because of Bela). Right now I am working with 8 "Stars" and when you press a button (right now on a midi Controller) it starts an ADSR Envelope that controls a Bandpass Filtered noise sound. You can chose different scales like Overtones, Pentatonic, .... . Additionaly I have added atmospheric sounds like water and waves/wind to create a soothing atmosphere. What I want to do now (and where I do not know how to achieve this) is:
I would like to integrate a Loop Function, that saves all the Input Data (Numbers and the Time when they are triggered). It should start to record the Data when the first Sound is triggered and then when there was no Input for a certain threshold (like 5 - 10 sec) it should play back the recorded Data in a Loop.
For the Atmosphere I also would like to add a soothing tonal drone that fits the Sound of the Scale of the Resonating Noise. I tried something with a phasor~ an long attack and release and a bit of filtering ... but it really does not sound good and soothing now. Any suggestions on how to get an atmospheric soothing slowly changing drone like tonal sound would be of big help!
