Most users with this issue have had to return the device. This issue only affects a small number of people, but the complaint has not been resolved. Some users complain that their PCs do not recognize MIDI controller. The volume slider seems to consistently cause problems, as it will not reach a minimum or maximum volume, operating only between 30% and 80%. While this would not be problematic for electronic music and simple chords or melodies, musicians wanting to play more complex compositions may have difficulty.
Users of this product have complained that they have to press down very hard to get enough volume from the keys. The velocity sensitivity on the controller keys could stand to be improved, as the keys on this keyboard are a little stiff. This keyboard has stiff keys which influence its sensitivity.
