Header rework, a status icon that actually tells you where you stand, and metadata that
survives a restart.
What changed since 1.3.1
The header lost its words. The controller count, the Device button and the status pill
were three ways of saying "who am I talking to". They are now one control with two halves:
the status opens the device panel, the count opens the controllers panel. Both panels are
unchanged. Every remaining label became the icon that already meant the same thing — words
were the first thing to run out of room on a phone.
One status icon, shape and colour. Shape is the role: a plain dot is an ordinary
controller, a dot with arcs is the web host — the machine publishing mp32-control.local
and serving the phones and tablets. Colour is the connection: green live, amber
reachable but in standby or re-establishing after a handover, red nothing there.
Standby is amber rather than green on purpose — the unit answers, but no audio is passing.
A phone lights up beside it while a handheld or another computer is actually on the web
interface, and goes out when none is. It shows only on the web host, and only in the desktop
window: a phone looking at the panel does not need to be told a phone is connected.
Metadata now survives a controller restart. Channel names, colours, groups and shared
notes were held in memory only. Restarting a controller emptied it, and the first browser to
reconnect re-seeded whatever it still held — including values deleted while that browser was
closed. Deletions came back. The field set is now persisted and written atomically, so the
network's current state outlives the process and a stale copy loses instead of winning.
Downloads
macOS (Apple Silicon) — MP32-Control-1.3.2-macOS-arm64.zip
Windows — MP32-Control-1.3.2-windows-build-kit.zip. A build kit, not an executable:
PyInstaller cannot cross-compile, so the .exe is produced on a Windows machine. Unzip and
read START HERE.txt. Two things usually go wrong: Python's "Add to PATH" checkbox, and the
Edge WebView2 runtime, without which the window opens blank.
Read this before installing
The macOS build is ad-hoc signed. On any Mac other than the one that built it, the first
launch is blocked: right-click the app → Open → Open, once. After that it starts normally.
The Windows build kit has never been run. The scripts, installer and guide are written
and internally consistent, but nobody has built this on Windows yet.
The HTTP control API has no authentication. Anyone who can reach port 8765 can change
gain, phantom power, input type and presets. Deliberate for a trusted studio LAN — never
port-forward it, never run it on untrusted Wi-Fi.
48 V phantom power can damage equipment that is not designed for it. Check what is
connected before enabling phantom or any bulk control.
Verified on hardware
Built with the physical device preflight active: the gate connected to an MP32, validated a
32-channel configuration and observed live telemetry before packaging. 162 automated checks
pass, including a new suite covering metadata persistence.
Not verified: two units on one network, any other preamp model, and cross-machine failover
between Mac, Windows and iPad. docs/VERIFICATION.md tracks what is proven and what is not.
