For Arts+Tech we are creating a series of noise circuits to explore the types of sounds and effects we would like to be in our final noise machine. Using the 4093 or NAND IC chip we are experimenting with gating multiple oscillators (from one chip) signals at particular frequencies thereby setting the tonal range we want to work with. This is helpful to gate out the very high squeeling frequenices that quickly move out of audible range. Another test is with feedback, taking the output from one oscillator and sending this to the input of another this creates very interesting patterns. When we left these drone oscillators playing over a period of time, the effect was of them ‘playing themselves’, with chaos and chance elements occurring …. very exciting!
