So what does VEL and DYN do? VEL controls the attack of the note. Keyboard players know what I'm talking about. Imagine playing the piano. If you strike the key fast, it makes a very different sound than if you strike the key slowly. Note that this is different from how loud the sound is--that is controlled by DYN. So VEL is basically how fast or how slowly the note is sounded out while DYN is how loud or soft the note actually is--meaning, the volume. VEL and DYN go hand in hand.
You're probably wondering, in terms of vocals, what does this mean? DYN for vocals is pretty easy to understand--it's how loudly or softly you are singing. But for VEL? Imagine if you are singing slowly. You are stretching the sounds of each word as you sing. This is especially pronounced with consonants. Trying singing the word "say" slowly. You'll see that you are slurring that "s" sound in the beginning--sssssay.

A good way to practice using VEL and DYN is to take a real singer and try to duplicate it with Vocaloid. In fact, you're all probably familiar with this since most of you use Vocaloid to do covers of songs. But many of you may be concentrating on the phonetics, trying to get the pronunciation right. Of course, that's the most important thing, but tweaking the parameters like VEL and DYN goes a long way into making the performance sound more human.

the notes, especially the beginning consonant sounds
We can go to the Menu Bar and select View and choose Control Parameters to display the parameter grid at the bottom. Select DYN (the word will turn aqua) and use the trusty pencil tool to adjust the height of the DYN bars for each lyric. I've lowered the values across the board, but especially for words like "say" and "head" to emphasize the slurring of the beginning consonant sound.

selected, we can add in some subtle volume swells to make
the vocals more realistic
You can see from the picture that I've drawn in some volume swells. For some lyrics, I've made it louder in the beginning, and for other lyrics, I've made it louder towards the end, especially if it's a long, drawn out lyric. I probably overdid it in the beginning because when Emmy sings, "Say you'll love me," she is pretty steady with the volume across the board here, so that part really only needed some very minor adjustments.
Here is a clip of Gumi singing this part. So what do you think? Does Gumi do a good job of emulating Emmy?
Give it a try! Download the Emmy Rossum part and try to duplicate it in Vocaloid and let me know how you did! Oh, one other thing--I also adjusted the vibrato in several spots. Emmy uses a lot of vibrato, and you can really hear it in the words "head" and "talk."
Until next time, keep rocking!
