Mixing & Mastering Engineers, Producers & Songwriters who worked with SeMi

Welcome to Ultra Mastering — where your music gets the professional mix and master it deserves.

I am ready to work! I got a powerful mezzo soprano vocal, can sing a very different range from quite low to quite high but not too high. I sing professionally for 20 years. I had a lot of vocal training during my whole life and I have great vocals techniques.

Hear the difference from 15+ years of professional experience.

I was born in Buenos Aires, Argentina. I am a guitarist, composer, arranger, director and music producer. I'm a recording and mixing engineer, based in my studio in downtown Buenos Aires. In the last 20 years, in addition to live performances, workshops seminars and recordings, I have scored music for films and theatre

I will provide you with the guitar sound you are looking for! Acoustic, electric or nylon string, I do it all. Good sound and feel are my no. 1 priority. Just send me your track and I'll do the rest 🎸

I'm not like everybody else.

I rap with bilingual versatility, high-energy songwriting creativity, and have a personality that electrifies! I also ranked #1 until the Semi-Finals in Timbaland’s competition. I can create freestyles, covers, originals, and standout performances with soul and adaptability. I currently work with well-known R&B groups, and have access to studios.
