Now I using E 09 in ,it"s a budget keyboard and also some good quality tone like vibs,string,guitar,santur,siter,flute,bass,many kinds of sax,group violine and violin although these are better play with using user section adding duel tone for separate tone. Many user have no idea about using transpose-so I can give an idea.....press numeric button -again press numeric and transpose hold and let to light function key with note lock status on light board-just one,two,three times leave the buttons off function key please.If the transpose button not lighting use same process again and just see transpose button lighting or not,When change tone or user performance must be lightened the transpose button....thanks
