Global Controls (Bottom Row)
The bottom row holds the global controls that shape the overall signal flow — Boost, Drive, Crossover, Focus, Fund, Mix, Auto Gain, Delta, Mono, and Output. These apply to the whole plugin, not individual harmonics. (Boost has its own section below.)
Drive
−12 dB to +24 dB
Drives the input into the harmonic generator. More drive = more saturation and stronger harmonics across all active bands.
Crossover
60 Hz to 1000 Hz
Sets the frequency split point. Everything below gets harmonically processed; everything above passes through clean. Also draggable directly on the spectrum display.
Focus
60 Hz to 1000 Hz
A low-pass on the generator's input only — the clean output is untouched. Lower it to feed the generator a purer sub so complex or chordal bass makes clean harmonics instead of intermodulation. At 1000 Hz (default) it's fully open.
Fund
0% to 100%
Level of the clean low band underneath the harmonics. Keep it up for weight; pull it down and lean on the harmonics for the "missing fundamental" effect — the ear rebuilds the pitch on speakers that can't reproduce the sub.
Mix
0% to 100%
Blends in the generated harmonics. The clean bands stay put, so no setting combs the crossover. At 100% you hear the full harmonic addition; lower values keep the enhancement subtle over the original bass.
Auto Gain
On / Off
Automatic level compensation on the enhanced low band. As you add harmonics or drive, Crane trims the band to hold a steady level so louder never fools you into thinking it's better. Great for honest A/B.
Delta
On / Off
Solos the added harmonics — you hear only what Crane is generating, at the current Mix. The fastest way to check what each band is contributing and to catch harshness before it hits the mix.
Mono
On / Off
Folds the low band to mono before the generator, so the harmonics are mono too. Keeps the bottom end phase-solid and centred on club and vinyl systems while the highs stay stereo.
Output
−24 dB to +12 dB
Master output gain applied after the mix blend. Use this to compensate for level increases caused by adding harmonics.
