AtlantaRoots & EDM vibes

Dilawar is a music producer whose roots come from Atlanta, and he brings the Atlanta EDM vibes with him. His influences come from Future Bass, Trap, and Dubstep, and he is exploring the very edges of genres in order to share a unique experience of sound and feeling. D Code hit the ground running with three albums released to date — with melodic and trap influences from some of the greatest artists of our day, D Code is setting high expectations in the EDM community. His duo artist project Zamantics adds an experimental dubstep influence to create an entirely distinct sound, heard on the album Galactic Guy.

“Exploring the very edges of genres — to share a unique experience of sound and feeling.”

As Music Masters Unlimited's founder, Dilawar runs the label and its mastering studio, working one-on-one with artists on every master. His passion for technology extends deep into the music production world: he leads the company's software development and built Stemy, MMU's macOS production app. He enjoys spending free time practicing the latest mixing technique or playing one of his many instruments.

Dilawar loves to collaborate with other artists, especially vocalists. Send us a message if you are interested in a collaboration and we will reach out for a demo. Listen to D Code and Zamantics on streaming platforms and YouTube.

Inside Stemy

Built by a mastering studio

Stemy comes from the same room and the same ears as the Music Masters Unlimited mastering service — the tools we wanted, built the way a studio would build them.

01 — Separation

AI stem separation

Pull any finished track apart into clean, workable stems — for remixes, sampling, practice, or rescue work on old mixes.

  • Standard tier — fast 4-stem separation: vocals, drums, bass, other
  • Neural tier — Mel-Band RoFormer models, up to 6 stems: vocals, drums, bass, guitar, piano, other
  • Drum-elements model — a dedicated split of the kit itself: kick, snare, hats, cymbals, and percussion
02 — Mastering

A native DSP mastering chain

No wrappers, no ports — a mastering chain built natively for the Mac, stage by stage.

  • Multiband processing for control across the spectrum
  • True-peak limiter and a master clipper for loudness that survives streaming conversion
  • Master Imager for stereo width, and a Dynamic Low-End tool for weight that stays tight
03 — Auto-Master

One click, three characters

Auto-Master reads your track and builds a finished master around the sound you're after.

  • Clean, Warm, and Loud profiles to set the direction
  • Can drive your own plugins, ranked by capability, when you want your sound in the chain
  • Loudness-targeted with a post-chain mix-health check, so “loud” never means “crushed”
04 — Analysis

Know your track, deeply

Stemy listens the way an engineer does and maps the whole song before you touch a control.

  • Beats, bars, BPM, and key mapped across the timeline
  • Loudness and song structure — sections, energy, and pace
  • Instrument activity — where every element actually plays
