I have been working on a loop in Logic Pro 9 and the tempo is 72.5bpm. If I wanted to change it to 73bpm how would I go about that? I have tried using the flex tool and also Varispeed but the string patch I used has almost a tremolo effect on it so when verispeed is activated to put in new bpm it comes out wobbly and glitchy. I don't have Ableton so is there another way to change tempo or perhaps an app? Oh and no, unfortunately they are not in midi form, they are .wav stems.
