This is probably something simple but it's driving me nuts. I took a MIDI file from online (By The Time I Get To Phoenix) and opened it in PT, then, while playing the track, I used the mixer to raise/lower the individual instruments to the volume I wanted - muting the melody instrument and adjusting the others to what I wanted and everything sounds fine......until...I stop the track to rewind and listen to my results and all the sliders go back to their original levels, negating everything I just did. How in the world do I make the sliders stay where I put them? When and if I get a decent track, I output it as a .wav file, then put it into Reaper and record my guitar along with it so it shouldn't be rocket surgery but I just can't get the sliders to stay put.
