I have an arrangement with stereo backing tracks for a set of songs and each stereo track is set as Master to control the tempo. Now I have a MIDI clip I'm sending to an external synth that I'd like to ramp from 20bpm to 135bpm, what's the best way to do this? As of right now I can't just automate the tempo in the Master track because "one or more clips are set as tempo master."

Thanks in advance!
