SUS4 Aurum 670
Flip Sus and it glues your whole mix into one slow, breathing pull. The kind of weight that makes people lean in without knowing why.
Studio · Label · Music Software
A boutique UK studio and label that invests in artists, and the maker of SUS4, a suite of 25 music apps and 25 studio-grade plugins built in a real working room.
SUS4 Apps · iPhone · iPad · Mac
25 focused music tools on the App Store. Four sit at the top of the range, built for musicians who are serious about getting better and getting things done.
FlagshipA full relative-pitch curriculum that starts at intervals and works up to chord progressions. The ear training that actually transfers to the instrument.
FlagshipPoint your camera at sheet music and get a clean, editable score back in seconds. Write lead sheets that look like they came from a publisher.
FlagshipSlow any audio down to a crawl, loop the bar you cannot work out, and figure out exactly what is being played without the guesswork.
SUS4 Plugins · AU · VST3
25 pro plugins in one bundle. Each behaves perfectly, until you flip its Sus switch and it does something it was never meant to: a compressor that gets louder where it should duck, a reverb that swells before the note. Weird, on purpose, and somehow musical.

COMP
Flip Sus and it glues your whole mix into one slow, breathing pull. The kind of weight that makes people lean in without knowing why.

COMP
Flip Sus and it’s all bite and attitude. It grabs a part by the scruff and drags it, snarling, to the front of the mix.

CHANNEL
Flip Sus and the whole clean channel goes through the looking-glass. A familiar sound, suddenly unrecognisable and alive.

COMP
Flip Sus and it rides your vocal into a slow, living swell. It breathes with the performance instead of pinning it down.

COMP
Flip Sus and it stops holding the mix still and starts shoving it forward. Pure energy and urgency, leaning right at the listener.

EQ
Flip Sus and it turns into an EQ that pushes back. Boosts where you cut, rings where you push, and still sounds musical doing it.
The Sus switch · on every single plugin
“Does that plugin even do anything?” Fair question. Most ‘character’ plugins do so little you couldn’t pick them in a blind test. So we went the other way. Every SUS4 plugin has a Sus switch. Off: the clean processor you trust on every mix. On: it does something it was never meant to. Weird, on purpose, and somehow musical.

Recording · Songwriting · Atmos
A boutique recording and songwriting studio in a quiet village with views over fields and hills. A 1904 Steinway Model K, brass, strings, a full drum kit, and ribbon and vintage-style microphones in a fully treated live room. Atmos mixing room for releases at any format. No upfront studio fee. The focus is on the music, not the clock.
