On the panel
- CrossoversFour bands with movable crossovers, at 120 Hz, 800 Hz and 5 kHz to start.
- PathStereo runs four compressors. Mid/Side runs eight, a mid and a side per band.

- SCExternal sidechain per band and per channel, so one band's mid can follow the key on its own.
- LookaheadUp to 10 ms, reported to the host as latency.
In Mid/Side mode it runs eight compressors, four bands on the centre and four on the sides. The band around 120 Hz can squeeze the mid hard and leave the sides alone, which is where the low end goes when the bass is fighting a wide synth. Stereo Multiband is there for when the mix doesn't need the split.
Processing modes
Stereo Multiband
Four compressors across four bands, working on the left and right channels together. The ordinary multiband, for a problem that sits in a frequency range.
Mid/Side
Eight compressors. Every band's mid and side carry a full independent parameter set, so a band can be held down in the centre and left open at the edges, or the reverse.
What it does
- Four bands with movable Linkwitz-Riley crossovers, defaulting to 120 Hz, 800 Hz and 5 kHz
- Two processing modes: Stereo Multiband runs four compressors, Mid/Side runs eight
- Independent threshold, ratio, attack, release and makeup per band, per channel
- Attack and release set directly in milliseconds, on the same scale in every band
All 9 features
- Solo, mute and bypass per band, so you can hear one band's work on its own
- External sidechain, switchable per band and per channel: the mid of one band can be keyed while its side is not
- Lookahead up to 10 ms, reported to the host as latency so the DAW can compensate
- Oversampling at 2x or 4x covers the whole engine, ballistics included
- One compressor circuit on every band: RMS detection, a wide 10 dB knee, and a release that stretches with the amount of reduction
