NerDie - 8 bit Noise Machine

NerDie is an 8-bit noise machine for iPad and iPhone: four oscillators, four LFOs, a summing tree with eight algorithms, a resonant low-pass filter and a one-bar sequencer. Thirty-two registers, integer arithmetic, mono output — the sound of a chip rather than a picture of one. The engine runs in whole numbers at a fixed chip rate. Overflow, wrap and quantisation are not added afterwards to make it sound old: they are the signal itself. It runs on its own or as an AUv3 instrument on a MIDI track in any host that loads them, in portrait and in landscape. THE MACHINE • 4 oscillators, 16 waveforms each, 19 to 1350 Hz • 4 LFOs, 8 shapes, moving pitch or volume — free-running in Hz, or multipliers of the clock up to x128 with the phase reset on every tick • 3 summing topologies x 3 nodes x 8 algorithms: addition, overflow, subtraction, ring modulation, XOR, FM and wave-shaping — 1,536 ways…
