Turning Machine
This is a recreation of the popular DIY Turing Machine Eurorack module. It consists of a recirculating 16 bit shift register, a random bit-flipper, and an 8 bit “DAC”. The main mod output is scaled to the 0-1 Audulus modulation standard and the 8 individual gates are tied to the bottom 8 bits of the register. The register length is adjustable from 1 to 16 bits and the probability that a bit will flip when recycled into bit 1 can be set from 0 to 100%. The register is advanced by a pulse on the clock input and a pulse on set or reset will set or clear all the bits in the register. The write 0 and write 1 triggers will write 0s or 1s into the register for as long as they are held. The module can be clocked at audio rates. (you will need to use a mod to audio converter for audio output)
