Polyend Tracker does not require any additional controls. It’s equipped with dedicated controls for fast-action programming. Polyend Tracker’s user interface offers different types of controls that can all be used alternatively to navigate and operate the instrument. Most of the values/data input in the Tracker is done by using the silicone grid pads, aluminum jog-wheel, the dedicated mechanical function keys, and the display corresponding screen keys. In most scenarios, these controllers can be used interchangeably – e.g. volume Fx1 value can be precisely entered using the jog-wheel scrolling for the desired value but also entered with a single press of the pad with the exact value.
