ThumbStick Controller
The Q182TS is a dual-axis ThumbStick Controller like that found on many popular video game systems. Two voltages are created, one for each axis of the ThumbStick, along with a Switch Gate when the ThumbStick is pressed. The ThumbStick returns to center when released. Perfect for pitch-bending, filter control and sequencer triggering.
The Q182TS is a double-space module so it can be mounted anywhere in a system or in a Box cabinet next to your keyboard and other controllers.
