I have been working on a STAB arrangement. I already laid the piano track and was currently working the harmony of the different voices. In order to listen to the voices alone I muted the piano and slow down the tempo to listen to the harmony of the voices. When I went back to the beggining, and set the tempo to the normal speed (120) the piano start at the initial tempo, but when the voices come in, they switch to the slow tempo that I was using just for reviewing purpose. I tried resetting the tempo but no luck!
