Dp4.5.2 Melodyne Bridge, Using Melodyne as a DP plugin Options

[blazingrythm]

I recently purchased Melodyne.
It's a great program for tuning, time shifting, or applying melodies to a drum track.
For instance, you can copy a vocal performance and paste it over a drum track and the drum track will play that melody.
I have the manual but can't get my head around how to apply Melodyne as a plugin.
The plugin is Melodyne Bridge.
You have to somehow record the soundbite in the 'Bridge" window but I've had no luck getting it to work.
Does anyone here know the procedure?
Thanks in advance for your valuable information.
