SUB+RM

Subharmonic generator & ring modulation

SUB+RM is a 2-in-1 analog effects module for Eurorack modular synthesizers.

SUB = subharmonic generator, primarily designed for sub-octaves but will behave differently (output different sub-harmonic notes) depending on input waveform and how hard you drive the input/dry level

RM = Ring modulation. Classic four-quadrant multiplier
