Tensors with serial numbers 108-066999 used a different circuit board that had less memory and a mono analog signal path. We plan to offer an upgrade board for longer looping times and stereo input/output. Unfortunately, we are waiting on some key components to arrive before we can start production. Due to the continuing supply chain issues, some parts are not scheduled to arrive until spring 2023.
The upgrade will be user installable when its available, and we will announce it on our newsletter and social media.
