This second function is activated when the user presses both the shift button and the button the function was assigned to at the same time, similar to a keyboard on a computer. This intuitive process allows any DJ to enhance their performance with twice the amount of usual effects and other functions. The TR-1 also features LED brightness control, letting the DJ control how bright the built-in LEDs are. This allows the equipment to be well lit in dark settings, so the DJ can still accurately use the controls. When compared to another piece of DJ equipment from Vestax, the VCI-300, the TR-1 has some advantages, including the shift button and adjustable LEDs.
