Even though I have used MC 2 for years, I'm finding MC7 a bit of a challenge. So much has changed. The 'help' documentation should be useful. But sometimes it is not.
I find that some sections of the screen, buttons, tabs etc are not indexed and even a search throws up either nothing or a multitude of subjects.
And even when the screenshot in 'help' matches exactly what I see on my own screen, it instructs you to 'press/click' this or that when it isn't even there. A typical example is Clip Properties. It tells me to click on it, when viewing the Mixstrip, but where the hell is it? I find out several hours later, while looking for something totally unrelated, that I can get it using 'shift-I'. <sigh>
Then I export a wav to convert to mp3 only to find it won't work. Why? Because it exported as 32-bit. Who knew? It wasn't obvious that it was exporting as 32-bit.
There's lots more but I don't have the time nor the inclination to go into them right now as I'm busy searching yet again for something 'hidden'. :-)
