Tensors with serial numbers 108-066999 used a different circuit board that had less memory and a mono analog signal path.  Some parts that we ordered in December, 2021 finally arrived (in September 2023), and we are currently getting everything ready to build the first batch of boards.  We plan to offer an upgrade board for longer looping times and stereo input/output by end of 2023.

Final price is TBD. We do not plan to make money on the upgrade kit, but we need to cover our costs and the circuit boards will be done by a different factory than our normal production due to the quantities.

The upgrade will be user installable when its available, and we will announce it on our newsletter and social media.
