No, I have no use for "Auto Bass" either nor for some of the more unusual voices, although the Flauto Cavo is a rather nice Italian stopped flute. However, with most modern digital instruments there are many facilities which you might not choose to use. With the AG2100 the options are all "hidden" down menus and can be selected or not. Once I had tinkered around with them I simply selected the voices I wanted to use to suit my playing, but could make a fresh selection if desired. Before purchasing I looked at different instruments and found that for what I could afford, the quality of finish and more importantly, the sound, of many were lacking. It is sad that there are now no true British manufacturers in this price bracket, only purveyors of re-badged Dutch and Italian models adapted to meet our tastes, and the cost of a UK custom built takes one into the realms of a small pipe instrument. I know which I would choose!
