Grain convolver?

i’ve been recently trying to gather information on the grain convolver concept that was developed by Tatsuya Takahashi, Christoph Hohnerlein and Maximilian Rest for the rbma sometime around 2018.

from what i understand it’s using supercollider to create grains of samples on the device to convolve with incoming audio, some people have claimed that they were using a lot of Convolution2L.

in one interview (https://www.redbullmusicacademy.com/lectures/granular-convolver-takahashi-rest-hohnerlein), Christoph Hohnerlein states:

You can check out what we’re doing on it. You have actual access to the code if you snoop around a bit. 

i’ve been snooping a bit, but couldn’t find the code yet, have any of you researched this technique and/or found snippets of their code?

best,
