EpromVerb3 1.1.0 — macOS (VST3, Audio Unit, standalone; universal: Apple silicon + Intel)
=========================================================================================
A rack reverb from 1990 running its own firmware: the plugin executes the unit's EPROM program and its DSP microcode.
The firmware image is NOT included. You need the 32 KB EPROM dump (the .BIN you have, 32,768 bytes).

INSTALL
1. Copy  EpromVerb3.vst3  into  ~/Library/Audio/Plug-Ins/VST3/  and  EpromVerb3.component  into
   ~/Library/Audio/Plug-Ins/Components/  (or the same folders under /Library for every user).
2. Give it the firmware, either way:
   a) copy your .BIN into that same folder, next to the plugin, and rename it  EpromVerb3.bin  , or
   b) open the plugin, click  LOAD EPROM...  (top right) and pick the .BIN. The path is remembered for every
      instance and both formats (stored in ~/Library/Application Support/EpromVerb3/EpromVerb3.settings).
   Always next to the plugin, never inside its bundle: changing a signed bundle breaks its signature.
3. Rescan plugins in your DAW (Logic: Settings > Plug-in Manager > Reset & Rescan).
   It is listed as "EpromVerb3" by "Unbranded" (Fx / Reverb).
   The header should read "EPROM v1.00 verified" and the display "000".

STANDALONE
Open EpromVerb3.app. Put EpromVerb3.bin next to it, or use LOAD EPROM... .
Audio devices: Options > Audio/MIDI Settings. The first launch asks for
microphone access (needed for audio input); if you said no: System Settings > Privacy & Security > Microphone.

USING IT
- INPUT / MIX / OUTPUT knobs are the unit's analog controls (MIX 0 % = dry, 100 % = effect only).
- The middle of the panel IS the unit: its display, LEDs and keys are driven by the firmware.
    PROGRAM, then three digits (or + / -) ............ select 000-199 (000-099 factory, 100-199 user)
    EDIT, then a function key (1 REVERB, 2 DELAY, 3 CHORUS, 4 EQ, 5 MIX, 6 CONFIG, 7 MOD, 8 MIDI, 9 MIDI PROG, 0 INT PROG)
    EDIT again ........................................ the function's second value (LED 1 / 2 beside EDIT)
    + / - .............................................. change the value shown
    STORE, then 100-199, then STORE ..................... save your edit as a user program
- The boxes along the bottom are the same values as host parameters: drag up/down (shift = fine), mouse wheel, or click
  the menu boxes. They follow the unit (program loads, front-panel edits, MIDI program changes) and you can automate them.
- MIDI into the plugin reaches the unit: program changes, and the controllers for its MOD routings.
- Your user programs (100-199) and the unit's MIDI settings live in its emulated EEPROM, saved with your project.
- The front panel responds while your DAW is processing audio (most DAWs keep processing when stopped).

If macOS says the plugin or app "cannot be checked for malicious software" (a build without notarisation):
right-click > Open once, or in Terminal:  xattr -dr com.apple.quarantine <path to the .vst3/.component/.app>
