C-Base Productions on SoundBetter

My name is Sebastian Schleinitz. I have been producing remixes since 2001 and have achieved many official releases so far (named "Captive of Society" or "Hartung & Schleinitz" Remix). Through remixing and own projects I worked on I deepened my skills in mixing and mastering (studies at HOFA Institute). So that I have also produced some bands.

I offer hybrid Mastering / STEM-Mastering / Mixing & Remixing. My skills are specially in EBM / Industrial to Synthpop till Techno, but i am open for all genres. If you need a loud and clear, but not squashed to death sounding master, or a killer remix, i am the right person for you!

The shown price for mixing understands incl. mastering.
If you want only mixing or a "Stem-Mastering" please hit me a message for the pricing.

So far i have worked for example with bands like AGONOIZE / MEGAHERZ / SOLITARY EXPERIMENTS / SUICIDE COMMANDO / DIN[A]TOD /

  1. Review by Lauren L.

    Sebastian always does a great job! Quick turnaround and gave my track that final touch it needed to really feel complete.

  2. Review by Daniel B.

    Sebastian did a fantastic job with mixing, mastering, and then remixing the song into its best possible version. The original mix sounds great, and the remix is groovy, creative, and totally unique from the original in a very cool way. He was clear and communicative about his schedule and deadlines, and worked well with feedback. Great experience.

  3. Review by Daniel B.

    Sebastian did a fantastic job mixing and mastering my song. I was particularly impressed with his ability to give each track space in the mix and let the melodic elements drive the song. His creative approach exceeded my expectations. He was also pleasant to work with, both communicative and friendly. Great experience

    A beautiful mastering. Absolutely the highest level that C-Base has conjured up. He's very talented. I love the song now, although it was a problem child before. C-Base got it all! Highly recommended.

  20. Review by Miklos J.

    Second time I worked with Sebastian. He's just finished my new single and I didn't even think about to look for anyone else with the 3-song minialbum because I was so satisfied with the job he's done. Everything is so clear but have that vintage vibe what I really like. It's really funny listening to my mixes now, after heard the masters: I thought that I was almost done and just needed that last touch but the difference I can hear now is magical. Thanks again C-Base! Looking forward to the next

Interview with C-Base Productions

  1. Q: What type of music do you usually work on?

  2. A: I am totally open for all genres, but the most stuff i have worked on so far is electronic music. Espechially the darker styles like EBM / Darkelectro / Darktechno / Industrial, but also Synthpop or Rap stuff.

  3. Q: What's your strongest skill?

  4. A: I think one of my best qualities is that I can put myself in the customer's shoes and get a good idea of what THEY wants.

  5. Q: Describe the most common type of work you do for your clients.

  6. A: Remixing, Mastering & Mixing. All this I do in a creative way, when mixing I do what the song tells me and I work to an image that is created in my head. In mixing and especially in mastering I focus on the needs of the client. It's always good if they know what they want to sound like and provide me some reference tracks. But sometimes it's also the case that they trust me completely and just say "please make it sound nice!". I'm happy when the customer is happy :-)

  7. Q: What other musicians or music production professionals inspire you?

  8. A: Ohh, it`s hard to say names, because i listen to many types of music and if its nicely produced, i can get something out of it. One name for shure is Mr. Haiwatt - Ken Marshall, i love seeing his sessions on youtube, especially when he restore some "Skinny Pupppy" or "Front Line Assembly" sessions from his archives.

  9. Q: What's your typical work process?

  10. A: The client send me a Track for Mixing & Mastering, the first step is always a intensive listening session. Than i asked for reference tracks, or sound wishes of the client. maybe sometime i have some additional ideas to the song, than i asked, if its okay, when i make some suggestions to it. In Remixing it is another thing, there i do what i wan`t because the client asked me for this remix, because thay like me other remixes. For shure, here it is also possible, when the client comes with some key data... like "i whant a remix for the club" than i of course will ensure that this remix will work in the club.

  11. Q: Analog or digital and why?

  12. A: I go for Hybrid! Digital in the Box definately wins in therms of workflow, but the warmth and depth of an analog EQ or Compressor is very, very hard to achive with plugins.

  13. Q: Tell us about a project you worked on you are especially proud of and why. What was your role?

  14. A: Very proud i am of the Cover Version for the famous Johan Van Roy (Suicide Commando) that i did with my Project "Captive of Society" Back in the days for his X20 Box. It was a pleasure to do that, and so crazy that he asked us to do that.

  15. Q: What are you working on at the moment?

  16. A: Currentely i am workling on the new "Full Contact69" Album and a very new Projekt called "Aktion Fiasko" there are some killer stuff comming. Electronic Punks are not dead! :-)

  17. Q: What's your 'promise' to your clients?

  18. A: The Job is done, if the Client is happy.

  19. Q: Can you share one music production tip?

  20. A: Hmmm, simple but true. Very often "less is more"! Do not overload your songs, focus on the key elements, than its also way easyer to get a clear mix and a loud master.

  21. Q: Tell us about your studio setup.

  22. A: The heart of my studio is my PC-Workstation with the DAW Cubase Pro. I Like working in the Box, because the Workflow is so much easyer. But some piece of Analog Hardware i also have, for example the most stuff from "Tegeler Audiomanufaktur" is controlled digital, with presets and total recall via one click, i love that!
