PoopBox: A Max For Live Emulation of The Hordijk Blippoo Box
The legendary Hordijk Blippoo box makes chaotic beeps and boops and gastric sounds using feedback.
The device takes two oscillators and cross modulates them. It generates further control signals for these oscillators using the resultant signals. The square wave scratchings are then passed through an emulation of Hordijk’s Twin Peak filter.
