So frustrated even just reading this thread. No one has explained why you cant record a new track without rerecording the previous tracks over again. Muting is not the answer because if you mute you cannot hear to play or sing along. Ive looked all over for a setting that will allow me to accomplish this most basic feature in track recording and nothing presents itself. Im using mix pad on my android tablet so thats already a high stress situation. Has anyone found a solution yet?
