The LMK4+ is the high-end model among the Doepfer master keyboards with various possibilities for controlling sound and playing. Its high-quality hammer-action keyboard, the many controllers and connection options as well as the indispensable sturdy case in the format and design of a touring flight case make it one of the most popular devices of its kind for professional use.

It features 8 split zones, 128 memories and many free programmable controllers ( 2 wheels, 2 sliders, one rotary potentiometer, 2 footcontrol connectors, 2 footswitch connectors, after touch).
