Yes! Nori Grains is a granular synth! Here's an OLED screenshot of what the knobs do:
From the organelle.io repository: The Nori Grains sampler allows you to record a sound and create a randomized polyphonic grain cloud from the sound. Press and hold the Aux button to record (minimum 0.5 sec - maximum 6 seconds). Each key will activate a grain voice that fades in and out. The fade in / out time is controllable with knob 3 from <1 sec to over 60 seconds allowing you to create a slowly evolving grain clouds. The other knobs control density, detuning, and grain size.
