﻿================================================================

 SORYNO COMP Free  v1.0.2

 Compressor (Windows / VST3)

================================================================



Thank you for choosing SORYNO COMP Free.



This is a free version, but it is not a cut-down demo. The aim is

that it is enough to finish the job on its own. There is no time

limit, no restriction on how many times a feature can be used and

no license activation, so it runs offline.



A compressor built around showing what it is doing, so you can

see the level and the gain reduction while you work.





[ SYSTEM REQUIREMENTS ]

----------------------------------------------------------------



  OS              Windows 10 / 11 (64-bit)

  Format          VST3

  Sample rates    44.1 / 48 / 96 / 192 kHz

  Channels        mono / stereo

  Extra runtime   none



  The Visual C++ redistributable is NOT required. Everything the

  plug-in needs is inside the plug-in itself.



  There is no macOS version and no AAX version.





[ HOW TO INSTALL ]

----------------------------------------------------------------



  Double-click  Install.bat



  Administrator rights are NOT required.



  (The other batch file in this folder has a Japanese name and is

  exactly the same thing. Either one will do.)



  It installs to:

    %LOCALAPPDATA%\Programs\Common\VST3



  This is an official VST3 location defined by the VST3 standard.

  The installer also looks in the system-wide VST3 folder and moves

  any older copy of the same plug-in out of the way. It moves it to

  a backup folder; nothing is deleted.



  When it has finished, rescan your plug-ins in your DAW.



  * Prefer to install by hand?

    Copy the folder

      VST3\SORYNO COMP Free.vst3

    into

      %LOCALAPPDATA%\Programs\Common\VST3

    That is all the installer does.



  * About the Windows warning

    Windows may show "Windows protected your PC". That is because

    we have not bought a code-signing certificate, not because

    there is anything wrong with the file. Choose "More info",

    then "Run anyway".



  * To uninstall

    powershell -ExecutionPolicy Bypass -File install.ps1 -Uninstall





[ WHAT IT DOES ]

----------------------------------------------------------------



  THRESHOLD   -60 to 0 dB       Level above which it starts working.

  RATIO       1:1 to inf:1      How much of the excess is held back.

  ATTACK      0.02 to 250 ms    How fast it starts working.

  RELEASE     5 to 2500 ms      How fast it lets go.

  MAKEUP      -12 to +24 dB     Brings the level back up.

  IN / OUT    -24 to +24 dB     Input and output gain.



  - History graph of level and gain reduction.

      You can see when, and by how much, it worked.

  - Transfer curve.

      Shows the input/output relationship, with a moving dot for

      the level playing right now.

  - 14 presets.



  Fixed in the free version (adjustable in Pro):

    KNEE 6.0 dB (a gentle soft knee) / MIX 100% / Peak detection /

    stereo / no look-ahead.



  These are not missing features. They are set to values that work,

  and the plug-in does its job with them as they are.



  Shared controls:

    A / B       Compare two settings (B>A copies B onto A).

    UNDO/REDO   Step back and forward.

    INIT        Return to the default setting.

    BYPASS      Stop processing.

    Window      Drag a corner to resize.



  * About BYPASS

    Unlike most plug-ins, the latency is still applied while BYPASS

    is on. Switching it does not move the timing of the audio, so

    you can compare against other tracks freely. This is deliberate.





[ WHAT SORYNO COMP Pro ADDS ]

----------------------------------------------------------------



  If the free version is not enough, consider Pro. It works the

  same way and adds the following.



  - A full side-chain section.

      Drive it from another track (duck the bass with the kick, and

      so on), with HPF / LPF to focus the detection and a LISTEN

      button to hear what the detector hears.

  - KNEE (0 to 30 dB). Make the onset sharp or gradual.

  - MIX (parallel compression). Blend the dry signal back in.

  - DETECTION (Peak / RMS). Judge by the instant or by the average.

  - Stereo / Mid-Side and stereo link.

  - LOOKAHEAD, so transients are not missed.

  - Six characters (Clean / Punch / Opto / VCA / FET / Bus).

  - AUTO GAIN and AUTO RELEASE.

  - 38 presets.



  Pro versions are in preparation and are not on sale yet.

  See the SORYNO shop on BOOTH.





[ RELEASE NOTIFICATIONS ]
----------------------------------------------------------------

  SORYNO COMP Free is free. When a new version is released you can
  download it from the same BOOTH page at any time.

  The plug-in checks for a newer version when its window opens. If one
  exists it shows a notice. It never installs anything by itself.

  * To switch the check off
    Right-click anywhere on the plug-in window and untick
    "Check for updates". It works over knobs and graphs too.

    - The change takes effect the next time you open the plug-in.
    - The setting is saved with your song (the DAW project), not as a
      machine-wide preference.

  * What the check sends
    Nothing.
    It reads one small text file hosted on GitHub. No information
    about you, your computer, your projects or how you use the
    plug-in is ever sent. The version comparison happens on your
    machine. If there is no connection it simply does nothing.

[ WHAT CHANGED IN v1.0.2 ]
----------------------------------------------------------------

  * The sound is bit-identical to v1.0.0 and v1.0.1.
    (Checked by nulling the old build against the new one:
     the difference is exactly zero.)
    What changed is the display and the handling:

  - Right-click now works anywhere on the window, including over
    knobs and graphs (this is where the update-check switch lives)
  - A failed preset save is now reported instead of being silent
  - A damaged preset file is moved aside instead of overwritten
  - The "check for updates" setting is no longer reset by presets
  - The update notice is now a readable card
  - Gain-reduction meters now fall back at the same rate

[ HOW TO CHECK THE VERSION ]
----------------------------------------------------------------

  The version is shown at the top left of the window, to the
  right of the product name.

    V1.0.2

  To check the file itself, compare the hash below.

  SHA256 of
    VST3\SORYNO COMP Free.vst3\Contents\x86_64-win\SORYNO COMP Free.vst3

    BDE0B9D03D591EA321BDEF2283270F52DDA516027FBC48AED24BFA3CFD03C7D0

  To check it, paste this into PowerShell from this folder:

    Get-FileHash "VST3\SORYNO COMP Free.vst3\Contents\x86_64-win\SORYNO COMP Free.vst3"


[ IF SOMETHING GOES WRONG ]

----------------------------------------------------------------



  It does not appear in my DAW

    -> Rescan your plug-ins. If it still does not appear, check

       whether an older copy is left somewhere else.



  The sound arrives late

    -> Check that delay compensation is on in your DAW. This

       plug-in reports its latency correctly.



  The sound changes when I press BYPASS

    -> Latency is still applied while BYPASS is on (by design).

       The sound itself is not altered.
