It seems safe to assume that Grain from 2hp is the smallest granular processor to date. The miniature size of the module, however, hides its potential for extreme sonic atomization. Any incoming sound gets split into small particles, the amount and positioning of which is definable by the density parameter. The resulting texture can be further repitched via frequency control or using external voltages applied to the v/8 input. A 'mix' control helps in establishing the right balance between the original and processed sounds.
2hp has four new modules for NAMM 2019. Bell is a physical modeling bell sound that is the sound source for the first half of this video, then it is switched to sine which is a sine VCO with built in wave-folder and sub-oscillator output. These modules are run through Grain in the video, which is a granular synthesis processor module. 2hp also has a new module called DC which generates DC offsets which is a useful utility module.
