Are the two incompatible?

Win 7 Home Premium Service Pack 1
Audacity 2.0.4 installed by .exe

Been puttering around with Audacity as a hobby, creating ringtones/soundbites from old pop tunes - having fun and learning quite a bit. But a couple of times, it has seemed like if the tempo effect was applied to a track in which the envelope tool had been used, the enveloping was reversed before the tempo was changed. Are the two incompatible? Or does tempo have to precede envelope? There was no warning the reversal would happen.

Thanks in advance…

Not sure about the issue, but a quick heads-up: 2.0.4 is quite old now. I suggest you grab 2.2.0 (it may even have that issue fixed!)

The current version is Audacity 2.2.2.

That’s what I get for typing a response when tired… oops. haha
