Mixed By Koen Heldens is the home of Koen Heldens: in-house mixing engineer for 3x GRAMMY nominee Dem Jointz and his "U Made Us What We Are Brand" & is an officially listed Apple Mastered for iTunes (MFiT) partner.

Born in The Netherlands, Koen moved to Los Angeles at the age of 19. At an early age it was obvious he was destined for a career in the music industry; beginning with attending music school at the tender age of 6 and accelerating through his teenage years as a music producer. Koen’s love for music production was eventually replaced by his passion for the art of mixing down music.

Not long after moving to Los Angeles, Koen gained the friendship of legendary GRAMMY® Award winning mixing engineer Dave Pensado (Michael Jackson, Beyoncé, Elton John). Dave’s friendship proved to be instrumental in Koen’s development and career as a mixing engineer.

Koen’s unique talent didn’t go unnoticed and caught the attention of 3x GRAMMY Award nominated producer Dem Jointz (Dr. Dre, Janet Jackson, Rihanna). The two forged an amazing chemistry which led to Koen becoming the in-house mixer for Dem’s “U Made Us what We Are” brand.

With his extensive technical, creative background and humble approach; Koen continues to work with the who’s who of today’s popular music and is a trusted face for top pro audio brands and an officially listed partner with Apple® for Mastered for iTunes® (MFiT).

Koen is represented by Danny Carter and Denzil Foster of Pray & Floss Management and currently resides in Los Angeles, California.

    Excellent work, a pleasure to work with :)

    Koen Heldens, of hitmixing was the mixing engineer for my client's new pop/dance record. What I liked most about working with Koen is that he understood the fine balance we needed – pop/commercial and heavy house/electro beats. We wanted the record to showcase vocals and yet still have the production hit hard. Koen achieved this. Thank you.

Interview with Mixed By Koen Heldens

What's the biggest misconception about what you do?
That we can fix it in the mix or that we can turn something that sounds ok into something that sounds amazing. At the end of the day if your song sounds amazing, I will make it sound super amazing. But if your song sounds ok, I will make it sound just better.
How would you describe your style?
Very in-tune with the clients vision; therefore my style is additive instead of subtractive from the clients music.
Can you share one music production tip?
Less is more...
What type of music do you usually work on?
Mostly EDM, Pop, R&B, Rap and Hip-Hop.
What's your strongest skill?
Enhance the songs' vitals. These include the rhythm section, with an emphasis on dynamics and the low-end, vocals (bring them up front and in your face but not harsh and piercing) and creating a nice bedding of the instruments.
What do you bring to a song?
Over a decade of professional, award winning and multiplatinum certified experience. Including many national and international top 40 hits for guaranteed satisfied final results.
What's your typical work process?
Creative call with the client to ensure we are on the same page and that I understand their vision for the final mix.
Describe the most common type of work you do for your clients.
Most clients hire me for their mixing needs. To get their music to the next level and presentable for the public.
