Rotary Dial Emulation

This function permits use of LED buttons instead of the rotary dial, for situations where the rotary encoder is failing.

A jumpy rotary dial is an unfortunate feature of ageing TNRs. Firmware efforts have been made to improve the situation (See XXX), but in many cases, this is not sufficient. The encoder is repairable, but this requires some electronics skill and a degree of bravery…

Unfortunately, the rotary encoder is the only way to navigate the menu and access most menu items. This feature allows LED presses to be used instead, where pressing in the top half of the button grid moves the menu item up, and the bottom half moves it down.

This feature can be enabled and disabled via the System menu, under the setting “Rotary Emulation”

Importantly, this feature can also be force enabled by simultaneously holding [R1] and [R2] during power-on; this is used in the catch-22 case where activating the feature via the menu is not possible since the rotary encoder is so bad…

If the feature is enabled, the boot-up screen replaces the text “Advance” with “Emulate”.

Note that when active, the TNR default behavior changes : normally, LED presses while the menu is active result in notes being played on the grid, but when this feature is active, this will not happen since the LED presses are interpreted as
