Applying default transitions works well, as listed above.
Myself, I often like to add little 2 frame crossfades at the start and end of audio heads/tails. So…. If you’d like to change the DURATION of the audio transition, you just need to go into the preference panel. Under “General” you can tell premiere how many frames you’d like the audio transitions to be.
In FCP7 you can make individual duration lengths and easily apply them. In premiere, you have to set all audio durations globally and live with that limitation.
So, you know, it works, just different.
