Audacity version: 2.2.2
When changing the tempo of a selected track, I can only increase the percentage. Attempting to decrease the tempo into the negatives - or anything less than around 10, even - I get the following message (both for clicking ‘preview’ and for ‘ok’):
“Value not in range: 10.55 to 32705.31”
Strangely, attempting to ‘preview’ at a lower number still works as long as that number was the default when opening the change tempo window, but changing the slider/percentage number at all yields the aforementioned error.
