EpromVerb4 1.0.1 — macOS (VST3, Audio Unit, standalone; universal: Apple silicon + Intel)
=========================================================================================
A mid-1990s rack multi-effect 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 64 KB EPROM dump (the .BIN you have, 65,536 bytes).

INSTALL
1. Copy  EpromVerb4.vst3  into  ~/Library/Audio/Plug-Ins/VST3/  and  EpromVerb4.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  EpromVerb4.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/EpromVerb4/EpromVerb4.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 "EpromVerb4" by "Unbranded" (Fx / Reverb).
   The header should read "EPROM v1.03 verified" and the display "Classicl    CONCERT HALL".
   The first start of each new instance takes a moment: the unit initialises its battery RAM (128 user programs).

STANDALONE
Open EpromVerb4.app. Put EpromVerb4.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
- The display and the keys are the unit's own; the firmware drives them.
    PROG ............... program mode: turn the DATA WHEEL (drag up/down, or one detent per scroll notch) to step
                         through the programs; it stops when you stop, and spun fast it accelerates like the unit's
    PAGE ............... the algorithm's parameter pages; A B C D pick a value (it blinks), the wheel changes it
    hold A/B/C/D ....... help text for that value
    STORE .............. save as a user program (wheel picks the slot, STORE again confirms; its light blinks)
    UTIL ............... MIDI channel and program map, footswitch, Dry Defeat, dual-program mode
    INPUT + OUTPUT ..... pressed together: Auto Level (play your loudest signal for ~5 s)
    FOOT ............... the footswitch jack
- PROGRAM at the bottom is the host parameter: pick any of the 128 presets (P000-P127) or 128 user programs
  (U000-U127) from the list, automate it, or watch it follow the panel and MIDI.
- MIDI into the plugin reaches the unit: program changes (through its map; by default to the user programs), its
  real-time controllers, sysex.
- The unit's whole memory (user programs, edits, settings, levels) is saved with your project.
- The front panel responds while your DAW is processing audio (most DAWs keep processing when stopped).
- Latency: none at 48 kHz; at other sample rates the plugin converts to the unit's 48 kHz and tells your DAW.

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>
