For the volume problem go to the View then to Mixer (or just pess F3 for a quicker way) and for the V3 Tiny you are only limited to Reverb and Comp. You can turn off Reverb and mess around with Comp and pick up the volume a bit until it's good to you.
Which Vocaloid do you have by the way?

Suddenly started thinking about Piapro Studio, sorry
For English it should be fine to type out the full words, but for JPN it would be separate like: Ko ko ne ( which is Kokone)
