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
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.
