Just got this keyboard for the learning function. I can't figure out if one is supposed to play the key while it is flashing or wait for it to turn to a solid light. If I play the key while it is flashing it doesn't always register and the voice comes on with the finger to use. Now having listened to the piece prior to going into the practice mode I know the particular note is only to be played once. I played it while it was flashing but it requires the same note to be played again for the piece to continue. Would appreciate any input.
