In response to a customer who reported an issue when using foldback at 192 kHz sampling, we release new firmware for the UC1, v1.2.6. It adds just a patch for this bug, since in this customer’s words: “Outside of that one bug, the unit has been bulletproof”.
The update is done via a Windows computer. The new firmware can be found on the UC1 download page. Instructions for how to perform the update can be found in the UC1 manual on page 25.
