The PINK OSCILLATOR is a 4-VOICES-IN-ONE instrument I made using as its heart the CMOS Hex Schmitt Trigger Integrated Circuit. Nicolas Collins in his book "Handmade Electronic Music, The Art of Hardware Hacking," devotes the whole chapter 18th to describe how to use this IC to produce sounds in very interesting ways. I used four of its outputs, and implanted several resistors and capacitors of different values to get different pitchs. I also used several bodycontacs, potentiometers, photoresistors, blue LEDS (one for each voice) and switches. As an enclosure, I used a Radio Shack black plastic box which I painted in pink and chrome--4 colored bands in total, one for each voice. Each voice has its own output which I usually mix through a passive mixer.

(TIP: click all players so that they play at the same time, and you will hear a nice song))
