Hi Taike,

Welcome to the Technics Forum on SynthZone! You didn't specify whether or not you have a KN keyboard, and if so, which one. The manuals that accompany the instruments we buy do indeed leave a lot to be desired. Your suggestions make sense, but companies are unlikely to produce the "help" products you mention if their history to date is any indicator of their future intentions. Third parties do produce "help" products. I bought the KN6000 Tutorial Video and the Technote Workshop series of six videos and found them to be just what I needed as a beginning arranger keyboard player. I also purchased the "How Do I Do That" book authored by Alec Pagida from Keynote. It is an excellent guide book in my opinion. I hasten to add that I am a United States Air Force retiree and have no business connection with either entity. I mention these products to you in the event you are not aware they exist. There is additonal quality help available but you have to pay for it. In my case it was money well spent.

Best Regards, Chuck
