With the Decksaver Native Instruments Kontrol S49 MK2 Dust cover you protect your Kontrol S49 MIDI keyboard against dust, liquid and scratches. Dust causes defects on the rotary and push buttons. This allows a parameter within your audio software to jump when you turn a knob. This makes it difficult to create smooth transitions. Because of the cut-outs you leave the cables in the MIDI keyboard when you have finished producing. You also no longer have to worry about using a duster that makes it difficult to get between the buttons and faders. This way you can easily keep your studio dust-free.
