Six Missing has the kind of catalog that makes small details feel important. Led by Austin-based sound designer, mixer, and composer TJ Dumser, the project sits on the slower, more patient side of ambient music, where guitar loops, vintage synths, tape machines, and field recordings carry much of the weight. His releases on Nettwerk Music Group, including Patricia, Without Mind, Here For Now, and drift, sway, all point toward a process built on close listening. 

The sounds move slowly, the changes are subtle, and the production choices have to hold up under that kind of space. 

That mindset is one of the many outside-the-box applications we’ve seen BARK24 | DYN used for. It can help clean up harsh sample libraries, bring forward reverb tails, shape specific bands, and make fast level decisions without turning the process into a long technical detour.

That approach also fits the larger arc of Six Missing right now. 

His upcoming EP, Passed Self, continues a run of music centered on growth, transition, grief, anxiety, burnout, and presence, while recent milestones have pushed the project into larger spaces, including his 2025 selection as an Amazon Music Original artist for World Mental Health Day and a Times Square billboard. Even with that wider visibility, his studio process still comes back to careful decisions, imperfect analog sources, and trust in the ear. 

In this conversation, TJ breaks down how BARK24 | DYN fits into his ambient workflow, how he approaches movement as part of composition, and why subtractive mixing remains one of the most useful habits a producer can build.

Interview With Six Missing

What made you first start paying attention to movement in a sound as an ambient artist, beyond basic filter sweeps and reverb automations, and start seeing gain movement as a creative part of your ambient music?

For me, it really started in my TV mixing career — a lot of the skills and tools I've learned over my 20 years of mixing TV have carried right into my ambient work as Six Missing. 

The biggest thing I've learned is that before you go to push up the volume of one thing, pull down the volume of other parts first. You ultimately end up with a cleaner, more dynamic arrangement or mix that way.

In ambient music, where the changes can be slower and subtler, how do you decide when a sound needs compression, expansion, or level shaping?

I do a lot of listening and reacting quickly to whatever my gut is feeling — sometimes I hard commit those choices and just have to deal with my decisions and other times I work really fast and then let it simmer for a day or two before returning to it. 

It's usually when I let things sit for a day and come back with fresh ears that I can hear exactly what has to happen — and that normally is some form of band-focused compression or adjusting down the volume of a specific piece. Bark24 | Dyn allows me to do both quite easily and creatively.

What kinds of source sounds tend to benefit most from Bark24 | Dyn in your own ambient work? Are there any details it helps you hear that standard compressors may overlook?

I tend to use a lot of sample libraries that aren't made for "ambient" in particular which means they can be harsh and epic by design. I love pulling in wild and bombastic sounds to my ambient world - the magic is in the restraint for me. 

Before I got turned onto FSK I was doing a ton of EQ sculpting, which can be a bit tedious. Bark really allowed me to make some bold moves quickly and arrive at the place I'm hearing from the beginning, really has become a game-changer for my workflow. 

Outside of the sample libraries, I have an affinity for vintage analog gear, which, anyone who has used vintage kit will tell you, it can be unpredictable, making the post-production process just as much a part of the composition process.

Are there any special or different ways you think about expansion and upward detail control on the subtler textures and sounds you use in your music?

Yes, absolutely — the first thing that comes to mind for me is pushing up reverb tails. I love reverb so much, in fact, maybe too much. I'll easily put 2-4 reverbs on a sound without a second thought. Getting all the times and pre-delays right so that everything meshes together properly is a lot of fun. 

But then, using upward compression and expansion really lets the sonic character come through with reverb without making it a total washy mess… unless that's what you want, of course.

How does Bark24 | Dyn fit into your chain when you are treating a single sound versus the full mix?

I've been finding that Bark is great as a middle-of-the-chain cleanup/sculpting tool on an individual track.

I almost always listen to things as a full mix and then make decisions and moves within the mix versus solo-ing out a track (I'll of course do that when needed), but hearing the sound change the individual element within the larger context helps me make those choices smarter — with less "moves," too. 

My theory is that if you've got all the ingredients right, the master bus really shouldn't need all that much other than some final "safety net" stuff and a push of the overall level.

For producers making ambient music at home, what should they listen for first before reaching for a compressor or multiband processor?

The source, always go to the source. 

Make sure your signal chain is clean first, a lot of noise problems start with a cable. And then from there, if something is hard to hear, before you push that sound up or hit it with a compressor figure out what is masking it and pull that down. I'm a big believer in subtractive mixing — nothing should ever go over 0.0 on the fader, in my opinion. 

You can make a sound louder by lowering the surrounding parts. If you flip your thinking into that way, you'd be surprised how little you really need to "compress" or "fix" in a mix. Also, use your ears, trust them. And don't go by what anyone else does or says…including everything you just read from me 😄

Final Thoughts After Speaking With Six Missing

The big takeaway from TJ’s process is how much mileage you can get from listening before reacting. A lot of producers reach for compression when something feels buried, and his point about pulling other sounds down first is one of those simple mix habits that can change the entire way a track comes together. 

That is also where BARK24 | DYN feels useful in a real studio setting. It gives you a fast way to control specific areas of a sound, smooth out harshness, bring forward detail, and make level movement feel intentional without turning the process into a technical exercise.

What I like about this conversation is that TJ talks about the plugin from the perspective of someone who already knows how to solve mix problems without over-processing everything. He is using BARK24 | DYN to move faster, make better in-context decisions, and keep the source material intact, which feels especially relevant for ambient producers working with reverb, analog gear, field recordings, sample libraries, and slower arrangements where every small move is easy to hear.

For us, that is the real point of the tool: give producers control, keep the workflow moving, and help the music stay connected to the first idea that made it worth finishing.
