I would search help which is very good in Sonar. To explore this option, click on the small waveform icon in the top left of your sound, and you’ll notice the options Detect Tempo and Fit Tempo. This is a more automatic way to stretch the sounds to a specified tempo. Sonar cannot assume anything about tempo in wave files.īut there must be a disable of functionality, I'm sure of it and even remember reading about some keyboard shortcut for doing it. Another way to time stretch your sound is to use the Fit Tempo option in FL Studio 20. If not finding the disable of this stretching, I would just start another project with tempo set to what was the case you wanted(run audiosnap to find out), and then import to audio tracks from the old project. You must be able to turn this automatic audio stretch off is my assumption?

Have not been doing this in S8.5 yet, but there must be a default streching of the audio then. And of course rerecord audio on the part with changed tempo. In S4 at least, I often changed tempo of part of song and did that without any stretching of audio, but regretted it did not have a lock of clip start to the tempo map. The difficulty then is to find the correct tempo as recorded already. It sounded to me like OP just wants to change tempo of midi, not touching the audio.
