Upward and downward compression in four bands whose edges are harmonic numbers of the tracked note (default 1, 2-4, 5-16, 17 and up), so the same setting squashes the same harmonics on every note. A fixed-band OTT puts harmonic 2 of F1 and of C2 in different bands. - Three Linkwitz-Riley splits at sqrt(k(k+1)) x f0 with allpass compensation; at Depth 0 the bands sum within 0.05 dB. - Band level is the RMS over one period of the note, so heavy settings do not ripple at f0: a 40 Hz sine at Drive +12 dB, Time 10 % gets no harmonics above -110 dB. - At Depth 100 % on a saw, harmonics 1-12 change by the same amount on F1, C2 and G2 (within 0.2 dB). - Depth, Drive (on the detector only), Upward, Downward, Time, a gain per band; edges Low 1-8, Mid 2-16, High 3-48 with four splits. - Pitch from audio with about 67 ms lookahead, or from MIDI. - Editor: harmonic ruler with draggable edges, level and gain per band. - Catalog, workflows, editor-check, docs, signal chain and site copy.

# Signal chain
|
||
|
||
The order of the Bass Foundry plugins in a chain matters. Anvil, Lathe, Temper,
|
||
Knurl and Planish each detect the pitch from the audio they receive. If a plugin earlier
|
||
in the chain changes the audio, the pitch detection after it can go wrong.
|
||
|
||
## Recommended order
|
||
|
||
```text
|
||
bass track: synth → Lathe → Temper → Planish → Knurl → Patina → Weld
|
||
bass bus: Anvil → (bus compression, clipping) → Crucible
|
||
```
|
||
|
||
- **Lathe and Temper before Knurl.** They hear the plain synth, where the pitch
|
||
is clear.
|
||
- **Planish after the distortion, before Knurl.** OTT usually comes after
|
||
distortion. Planish's band edges follow the tracked note, so it also needs a
|
||
clear pitch: after Knurl, use MIDI.
|
||
- **Knurl last among the tracked plugins.** See below.
|
||
- **Patina after the tracked plugins.** It does not detect pitch, so the order
|
||
does not change its result.
|
||
- **Weld after every plugin with latency on its track.** Weld can delay its own
|
||
layer but cannot move it earlier. If FL Studio does not compensate the
|
||
sidechain route, any latency added after Weld's input on the main layer makes
|
||
that layer late.
|
||
- **Anvil on the bus, in MIDI mode when Knurl is in the chain.**
|
||
- **Crucible at the end of the chain you want to resample.**
|
||
|
||
## Knurl and pitch detection
|
||
|
||
Knurl's patterns make every second (or third) cycle quieter. That is a real
|
||
sub-octave in the signal, so a pitch detector after Knurl hears the note one
|
||
octave low, or with Triple an octave and a fifth low. Measured with the suite's
|
||
tracker on a saw bass:
|
||
|
||
- From C2 (65 Hz) upwards, Double, Fry (the default), Triple and Gallop make
|
||
the detector read the wrong octave for about 85 % of the note.
|
||
- Below C2 the false sub-octave is under 30 Hz, out of the detection range, so
|
||
low notes are tracked correctly.
|
||
- Level and time jitter add 5–25 false note starts per second. Anvil restarts
|
||
its phase on each, Lathe, Temper and Planish retune on each.
|
||
|
||
When a tracked plugin must come after Knurl, select **MIDI** as its pitch source
|
||
and route the bass's MIDI notes to it.
|
||
|
||
## Latency
|
||
|
||
Each tracked plugin adds its own lookahead: Anvil 80 ms, Lathe, Temper and
|
||
Planish about 67 ms, Knurl about 71 ms, Patina about 45 ms. A full chain is
|
||
about 400 ms. FL
|
||
Studio compensates this for playback and rendering, but playing a MIDI keyboard
|
||
through the full chain is not practical. Write with a shorter chain and add the
|
||
rest for the mix.
