docs/chain.md gives the plugin order for a bass track and the bus, the latency each plugin adds, and the measured octave error of downstream note trackers after Knurl: from C2 up the tracker reads an octave low about 85 % of the time, and timing jitter adds 5-25 false note starts per second. Knurl and Anvil guides point there and recommend MIDI as the pitch source after Knurl. docs/ideas.md gains the production-flow audit, next steps for every released plugin, new ideas (Forge, Planish, Quench, Scribe, Bevel, Peen) and a build order.

# Signal chain
|
||
|
||
The order of the Bass Foundry plugins in a chain matters. Anvil, Lathe, Temper
|
||
and Knurl 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 → 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.
|
||
- **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 and Temper 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 and Temper about
|
||
67 ms, Knurl about 71 ms, Patina about 45 ms. A full chain is about 330 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.
