Scared and shy

Hey, don't worry about feeling alone because of using vocaliods or are creating songs in any given genre.  I'm personally not a fan of the style of music you call k-pop nor the use of vocaloids in music. BUT.... that's my personal opinion and matters not, when I listen to your music. Just a few weeks ago, I don't recall if it was here or in another forum, somebody posted a song using vocaloids and let me just say, the fit of the vocaloid to the genre of the music and how it was mixed into the song was freaking amazing. Absolute best and most perfect use of a vocaloid I had ever heard. A human singer could not have done a better job.
 
We don't care what you do or why you do it. Here, the focus is on music in general and how best to record it so it sounds professional. I don't think I've ever seen anyone put down due to the genre or style of the music they record and present. We have folks who like and record everything from classical orchestral music, rock, country, pop,  to very off the wall indy stuff and everything in between. You simply fall into another interesting niche of this big thing called music.
 
And to answer your question..... yeah, there's a few folks here who do have and use the vocaloid plugins.
 
So don't feel alone or be shy about putting the music you create up into the songs forum for people to listen. You will find that people who don't like or listen to your chosen genre of music will often listen and comment regardless of their personal tastes in music.  They can, and often, will offer recording and production commentary that you can use to make your recordings sound better and improve your skills.
