I'd like to make some friends who enjoy talking about vocal synth and music making in general. I'm an aspiring vocal synth producer who has no clue on what to do. I have so many questions on music making and takes on vocal synth stuff. I own SynthV2, Solaria, Asterian, hxvoc, jovie and V6 Hatsune Miku.
