From the manufacturer:
Our monophonic granular sampler packs grand lo-fi sound into a small body. The 2nd generation of Bastl's instant classic reads wav samples from a microSD card and applies granular algorithms to them. With a vast collection of samples at your hands, you can do much more than simply trigger each one in turn. You can adjust start, end, sample rate (tuned or free run), crush, and envelope (attack release).
This is very lightly used and ships safely and swiftly in its original box! Feel free to call us with any questions you have.
