controllers for cubase. some questions

i want a controller that will make it easy to controll stuff.
i hate it when u need to move the mouse to increase or decrease some knob.
whats the best controller for cubase for volume control and other stuff (like opening edit instrument).

  1. i know steinberg has some controllers. are they the only ones in the market?


  2. it seems to me its very usefull, am i wrong?
    im just producing music for fun. is it worth the money?

  3. will the steinberg controllers work on the vst plugins and effects or only the cubase stuff?

  4. whats the newest controllers steinberg has?

  5. are there any other chip controllers that worth the money?

thank you!
