Anvil 1.15.0 (beta) - for Windows
Superseded by v1.15.0. This beta is kept for the record; the current release is a different instrument to look at.
Anvil 1.15.0 (beta) - for Windows
The first Windows release of Anvil - the whole instrument, in its own window.
Anvil is a synth-and-groovebox you can actually play: acid, wavetable, FM, string, drum,
granular and sampler engines in one instrument; a native step sequencer with chains, song rows
and scenes; a seven-slot FX rack with a drag-to-modulate matrix; a tuning studio (12 scales,
Scala .scl/.kbm import, live MTS SysEx receive); an import pipeline and a searchable library for
your own sounds; a store with 10 packs / 580 presets; and a recording desk that exports WAV,
stems, MIDI and Song Bundles. It is the same app as the free in-browser version at
moddys.net/anvil - this is that app in its own window, by itself. It is a MODDYS Foundry
instrument and a sibling of Pattern Forge.
A look at the Windows build:
What's new
- The desktop build itself. Anvil opens as a normal Windows program now - no browser, no
tabs. It serves its own files from an internal loopback address (what the audio worklet, the
clipboard and local storage want), grants MIDI and autoplay up front, and asks for nothing
else. - The instrument inside it is app build 1.15.0, with the newest app work included: the
Import & Library overlay (search-first, with format and pack facets, bulk actions and row
preview), the library overlay's resize / minimize / maximize controls, and the header fit fix- on top of the finished instrument (the tuning studio, acid step accents, the fill toggle,
full undo coverage, boot templates, a multi-tab save note, and tempo/root/key auto-tags from
WAV metadata).
- on top of the finished instrument (the tuning studio, acid step accents, the fill toggle,
In this release
- Anvil-1.15.0-Setup.exe - the installer. Per-user (no admin prompt), Start Menu entry and
desktop shortcut, upgrades install straight over the top, clean uninstall from Add/Remove.
It is not code-signed yet, so SmartScreen will say it hasn't seen this app before - More
info, then Run anyway. - Anvil-1.15.0-Setup.exe.zip - the same installer as a zip, byte for byte: the exact file
moddys.net/moddys-downloads.html serves. - Anvil-1.15.0-source.zip - the corresponding source for this build (AGPL-3.0-or-later): the
app build frozen into the installer, the src/ tree it is assembled from, the Electron shell,
the installer script, and the build and verification tools.
Good to know
- Windows 10/11, 64-bit. Everything the app needs is inside the install - the engine, all ten
packs, the help and the walkthrough - so it opens and plays with no network at all. The only
online parts are the family bridges (importing a Resonance Studio pack, the World Radio
hand-off), and those go out only when you click them. - Your projects, sessions, takes, installed packs and settings live in %APPDATA%\Anvil. The
installer never touches that folder; the uninstaller keeps it by default and asks before
deleting anything - installing again picks up where you left off. Nothing is sent anywhere. - Verified on this exact payload: the desktop suite driving the installed program
(31 checks - the worklet engine tier, a note played with a master-tap
witness, MIDI, the library overlay, zero page errors) and a silent install -> upgrade-over
install -> uninstall journey (28 checks) that leaves your data intact. The
build inside the installer is byte-identical to the one live at moddys.net/anvil (6ac4425b);
the app's own gates ran green first-lap (27 suites, hub 68 checks, fit 49; bench and alias
clean; the leak probe 11/11, file and live). - This is a beta - if something breaks, tell me: modtech@gmail.com.
