Melodic techno mastering that keeps the space and still drives the floor.
Long breakdowns, wide pads, a rolling bass and a kick that has to carry a peak-time room. ZERRRO Engine masters melodic techno with a reference profile built for exactly that balance. Hear it while it plays, pay only to download.

The engine’s default for Melodic House & Techno. Enough for the club, with room left for the breakdown to breathe.
Drive it harder for a peak-time set. Past that, pads flatten and the arps lose their shimmer.
Spotify and Apple Music turn loud files down anyway. The streaming version keeps the dynamics.
What a melodic techno master has to do
Melodic techno lives between two worlds: the emotion of the breakdown and the pressure of the drop. A master that only chases loudness wins the drop and loses everything else.
Width without a hollow centre
Pads and reverbs spread wide; kick, bass and lead stay firmly in the middle. The master adds width where it helps and keeps the low end mono.
Arps and leads that sparkle, not hiss
The top end carries the melody. It needs air above 10 kHz without turning sibilant when the limiter works harder in the drop.
A drop that lands after a long breakdown
The contrast is the point. Too much limiting makes the breakdown as loud as the drop, and the release disappears.
Hear it. Shape it. Then decide.

Upload & check
Bit depth, sample rate, true peak, clipping and loudness of your premaster are measured in seconds. If the file is already limited or clipping, you find out before anything is processed.

Pick Melodic & Progressive → Melodic House & Techno
The engine switches to a reference profile built from released melodic techno and melodic house, then adapts it to what your mix already has. Upload a reference track from your favourite label if you want a specific sound.

Shape it while it plays
Pick a character, drag the EQ dots, or type something like “wider pads, calmer highs”. Auto sets the loudness for the genre. Every change is audible while the track plays.

A/B and decide
Compare the master with your mix at matched loudness, read the measured LUFS and true peak, and render again for free if it is not there yet. You pay only when you download.

Questions producers ask
How loud should a melodic techno master be?
Around −9 LUFS integrated is a good club target and what the engine’s Auto setting picks for Melodic House & Techno; peak-time tracks can go to about −8. For streaming, around −14 LUFS at −1 dBTP; at club loudness the limiter ceiling is 0 dBTP.
Will the master make my pads narrower?
No. The stereo treatment keeps the low end mono and leaves the width of pads and effects in place. You can hear it in the A/B at matched loudness before you pay.
Can I use a reference track?
Yes. Upload one track and the target follows its tonal balance. Without a reference, pick Melodic House & Techno as the subgenre.
Is it free?
Hearing the full master is free, including the A/B against your mix. You pay one credit, from 2.99 EUR, only when you download.
