I am attempting to Tempo Map a recorded version of the 2nd movement of a Rachmaninoff Concerto with the hope that I can later get a different audio track (i.e., Music Minus One version of this same movement) to play back at the same tempo as the recorded version. Then, I will mix my piano part with it.
I am using Cubase 9 Pro (9.0.20).
I did a tempo detect on the recorded audio file. Of course, Cubase sets the tempo track time signature to 1/4. I left it that way so that I could mark every beat. I go to the time warp tool and then play back the audio and move the time warp markers to correspond to every beat. I found that during the process, I would periodically have to move a bunch of “downstream” markers (beyond where I am working) to the right (corresponding to the maximum tempo Cubase allows which is 300) to create room for the markers that I was working on. I have done 10:30 (I am at marker 590) out of 12:18.
According to the info line, the movement ends at 1184.108.40.206. My problem is that all of the remaining warp markers (from 590 up to 1124) are already as far to the right as possible. The Music Minus One file is in the project and is longer than the recorded track (it was recorded at a slower tempo). In theory, I can move markers beyond 1124 to the right. So, I do what I have been doing and move everything up to 1600 to the right. I have the project saved with 1135 to 1600 moved to the right (i.e. tempo set at 300). Then, I can move 1127 to 1135 to the right with no problems. As soon, as I touch marker 1126, the screen “flashes” (i.e., the warp markers jump) and the tempo is solid from 590 to 1600 at 300 leaving me no room to finish the tempo map from 590 to the end of the movement.
It has taken me many hours to do this and I would like to finish it. Is there any way to salvage this situation without losing the work I have already done? Is there a way to tell Cubase that there are fewer markers than 1124 so that the remaining markers can be stretched out to tempos less than 300? Would it help to glue another piece of audio to the end even though it has not been tempo detected?
Thank you for any help.
