@kittyspit was feeding live signal into the granular module and modulating the start/length and window using LFOs. The granular records into an internal buffer in a looping fashion, the internal buffer for live recording has a fixed length, and you activate it using the LIVE and REC buttons. REC starts/stops recording. First press LIVE and then press REC to get started.
The dub parameter controls mix between new and previous signal in the buffer and BLEND controls dry/wet of live input signal and granular output.
Also see the previous software update parameter list for the granular to understand what all the parameters do.
