The UTAU program is similar to vocaloid and is completely legal, you can download it for free. Also, if you want to use an voice sithesizer, just use UTAU. Seriously, people will hate you, and even if you buy an legal vocaloid, your song won't get famous no matter what. That happens a lot!! So, my recomendation for you is, if you have an fake vocaloid and you already told us that you have Kaito - not very smartyou can use it if you want, but don't ever post a song made by yourself anywhere on the internet.
It's offensive, and if you ever make an song with it and people discover that you used an illegal vocaloid, you'll be black listed in no time. Like you see, the other vocaloid fans can be very hostile towards people using illegal vocaloids. People who uses illegal vocaloids, or pocaloid, are not very well see from the other vocaloid fans. Before you go further on this, let me explain one thing.
