Noisemaker — Schwung module

A virtual-analog synth for Schwung on Ableton Move, ported from TAL NoiseMaker by Patrick Kunz (TAL / Togu Audio Line).

6-voice polyphony; dual oscillator + sub, ring mod, FM, oscillator sync, bitcrush, vintage noise
12 multimode filters — LP24/18/12/6, HP24, BP24, Notch, State-Variable LP/HP/BP, and two Moog models — with drive
Filter and amp ADSR, a free AD envelope, and TAL's spline Envelope Editor as a tempo-synced modulation source
Two tempo-syncable LFOs; velocity and pitch-wheel routing
Chorus, reverb, and delay
256 factory presets, plus import your own preset banks — see below
Four macros (oscillator Wave sweep, Osc 2 pitch, filter/amp envelope time) with on-screen value readouts
On-device canvas Editor with TAL-style panel grouping, a live filter-response curve, and oscillator/LFO waveform displays

Importing preset banks

Copy folders of loose .noisemakerpreset files (the format TAL NoiseMaker itself saves) into the module's own presets/ folder on the device — the same place OB-Xd takes its .fxb banks:

/data/UserData/schwung/modules/sound_generators/noisemaker/presets/

Each folder becomes a bank under Preset Bank on the module's root page, gathering presets from its own subfolders — so a pack laid out as MyPack/BASS, MyPack/LEAD, MyPack/PAD arrives as one MyPack bank. Presets sitting loose in the root form a (loose) bank.

There is no import step and nothing to refresh: the list is rebuilt each time you open the selector, so a folder copied over (schwung-manager's file browser at http://move.local:7700 is the easy way) is simply there. Presets are read straight from disk, one file at a time.

Updating the module leaves your banks alone. Uninstalling it deletes them, since they live inside the module folder — keep a copy elsewhere if they matter.

Both preset formats TAL has shipped are handled, including the older 10-item filter encoding used before NoiseMaker 1.7.

Install

Install from the Schwung module catalog via schwung-manager (http://move.local:7700), or grab the latest release tarball.

Build & deploy

./scripts/build.sh                                  # cross-compile dsp.so in Docker -> dist/noisemaker/ + tarball
MOVE_HOST=ableton@move.local ./scripts/install.sh   # deploy to the Move (atomic temp+mv)

install.sh copies each file via a temp name + mv -f so it never overwrites a live dsp.so in place. After deploying, reload the module (swap the slot synth out and back in, or run the workspace scripts/restart_move.sh).

To regenerate the on-device Editor after editing src/canvas.config.js:

node ../schwung-canvaskit/build.mjs src/canvas.config.js src/canvas.js

Tests

build.sh does not build the tests — each carries its own g++ line in its header comment, and they all need src/dsp/Engine/Lfo.cpp (the engine's only non-header file). Running a stale test binary reports a green suite that proves nothing.

g++ -O1 -std=c++14 -fpermissive -Wno-write-strings -Isrc/dsp -Isrc/dsp/Engine \
    tests/macro_test.cpp src/dsp/Engine/Lfo.cpp -o build/macro_test && ./build/macro_test

import_test and bank_test take an optional directory of .noisemakerpreset files to run against a real corpus. bank_test builds its own scratch module directory; point it somewhere harmless with -DNM_TEST_MODULE_DIR='"/some/scratch/dir"' so it never touches a real install.

Port notes

The engine (src/dsp/Engine, src/dsp/Effects) is vendored byte-verbatim from the DISTRHO-Ports TAL NoiseMaker source (the current TAL codebase) so upstream diffs stay clean. Notes:

Normalized param model. Every engine setter takes a normalized 0..1 value — continuous params and enums (which convert internally via calcComboBoxValue). The wrapper stores normalized values and converts only at the display boundary.
Envelope Editor ported JUCE-free. The stock spline envelope depends on JUCE (Array, juce::Point); src/dsp/EnvelopeEditor/juce_shim.h provides minimal replacements so the DSP builds without JUCE. The drawable editor UI is not included — the shape is fixed per preset; Amount, Speed, and Destination are controllable.
Factory data is generated. Presets are decoded from the engine's ProgramChunk (hex-encoded XML) into factory_bank.h, with per-preset envelope shapes in factory_splines.h. Filter-type indices are remapped from the presets' 10-slot scheme to the engine's 12 filters.
-fpermissive -Wno-write-strings — the vendored sources use a few MSVC-isms GCC rejects (class-qualified names in in-class member definitions in Decimator.h; string-literal-to-char*), downgraded to warnings rather than patched.
