My pro tools version is HD 10.3.7. When I arm and start recording, everything is working, the meters going up, wave form is bulit.
And when I stop it, the wave form (aka. region) immediately disappears. This happens only to short recordings. (As far as my test goes, it happens to recordings under 4 seconds).
However, the disappeared recording is saved in audio files. It's not just there anymore on pro tools edit view.
