How do I use the instrument tuner?
TX-6tutorialguide
The TX-6 has a built-in instrument tuner you can access directly from the mixer. It analyzes the pitch of a signal coming through one of the input channels.
Accessing the tuner
The tuner is listed as a feature in the TX-6 guide under its own dedicated section. However, the manual context provided does not include the detailed step-by-step instructions for operating the tuner, such as which button combination activates it or how to select a channel for tuning.
For the full tuner instructions, check the official guide directly at teenage.engineering/guides/tx-6 and navigate to the "instrument tuner" section.
