Mutable InstrumentsEurorack & modular

Random sampler / clocked random generator (discontinued)

Marbles is an 18HP Eurorack random sampler and clocked random generator from Mutable Instruments, produced from 2018 to 2022. It combines a jittery master clock and a two-channel random rhythm generator with three random voltage outputs that can be quantized with a programmable scale. The module is built around an STM32F405 at 168 MHz and a DAC8164.
