Not rated yet

ZeroBus is a HoRNet mix bus processor that combines a 31-band automatic EQ with compression that learns its threshold and makeup gain.

Its compressor has two modes, FAT (parallel, 1176-style) and GLUE (serial, SSL-style). It costs about $28.

Best for: Mix Bus, Drum Bus. Genres: all genres.

What it does

ZeroBus is HoRNet's "two-step mix bus processor": an automatic EQ balances the spectrum, then a compressor that learns your material glues the result. The idea is bus cohesion in a few seconds, without hunting for frequencies or thresholds.

AutoEQ: 31 bands of continuous spectral analysis and real-time balancing, with an amount control from 0 to 200% and a live EQ curve display.
GLUE mode: serial, SSL 4K-style bus compression aiming for about 9 dB of peak reduction, for smooth, transparent cohesion. It is the default mode since version 1.1.1.
FAT mode: parallel, 1176-style compression that drives the compressed path to about 19 dB of reduction, for a thicker, punchier sound.
Learning: automatic threshold learning and adaptive makeup gain, with a 0 to 100% compression amount.
Metering: a segmented gain reduction meter from 0 to -20 dB.
Practical touches: automatic 2x oversampling below 88.2 kHz, near-zero auto-compensated latency, and light, dark or auto themes.

Version 1.1.1 works at 44.1 to 192 kHz. A free demo is available, and HoRNet offers a 15-day money-back guarantee. It is also part of the ZeroBundle.

When to use it

ZeroBus is the better pick when you want a balanced, glued bus with two or three decisions instead of a full EQ and compressor setup. Compared with The Glue or SSL G-Master Buss Compressor, it adds automatic tonal balancing in front of the compression, but you give up the attack, release and ratio controls that make those plugins precise. Its GLUE mode aims for a similar SSL-style job, while FAT mode gives a parallel, 1176-flavoured squash that a single bus compressor can't do on its own. Compared with an assistant suite like Ozone 12, it is far cheaper and narrower: no limiter, imaging or reference matching.

Best for: mix bus and subgroup glue, drum and music buses, and quick demo mixes.
Genres: any.
Look elsewhere if: you want to set every EQ band and compressor parameter yourself; use Pro-C 3 or The Glue with a separate EQ.
