Minimal and deep tech mastering where every hit counts.
Minimal and deep tech have few elements, so every one of them is exposed. The master has to add weight and level without dulling the transients that carry the groove. ZERRRO Engine lets you hear exactly that.

The engine’s default for minimal house. Dry grooves lose their swing first when mastered too loud.
Deep tech that leans towards tech house can go a little louder.
The streaming master keeps the space between the hits.
What a minimal master has to preserve
In a sparse arrangement, silence is part of the groove. The master adds level to the hits, not to the space between them.
Transients with snap
Clicks, rims and hats carry the swing. Limiting rounds them off first.
A bassline with weight
Deep tech lives on a rolling, melodic bass. It needs to feel big on a club system without droning.
Space that stays space
Sparse tracks sound empty when the master raises the noise floor and reverbs with everything else.
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 House → Minimal / Deep Tech
The engine uses a reference profile built from released minimal and deep tech and adapts it to your mix. Tech House and Deep House are separate profiles in the same group.

Shape it while it plays
Choose a punchy or balanced character, drag the EQ dots, or type “tighter low end, snappier hats”. Auto sets the loudness for the subgenre.

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 minimal or deep tech master be?
Around −9 LUFS integrated for the club is what the engine’s Auto setting picks; deep tech closer to tech house can go to −8. The limiter ceiling is 0 dBTP at club loudness; for streaming, around −14 LUFS at −1 dBTP.
Will it kill the swing?
You hear the master while you shape it and compare it with your mix at matched loudness. If the groove stiffens, lower the loudness or choose a softer character.
Is there a profile for rominimal?
Use Minimal / Deep Tech and a softer character; the master follows your mix rather than forcing a curve.
Is it free?
