I can´t stop enjoying so many things I can do with my keyboards. Now I added a Korg NanoKontrol to my set up. At first I could not make it work and I thought I would return it to the store but later I realized how I had to set it up and now I can have at the tip of my fingers so many user programmable parameters with 18 buttons, 9 knobs and 9 sliders. So it is possible to control distant arrangers or synths with a tiny controller via the computer. There’s been so little and confusing information out there in the web and even in Korg forums that I just wanted to let you know: Yes it works with your Yamaha and Korg arranger.
