    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.

    Koen did an outstanding job mixing and mastering one of my tracks. He was easy to work with, was very quick with mix changes, and extremely professional in both producing and delivering the mix/master I wanted! Highly recommended.

Interview with hitmixing

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.
