Oh Derek Demo -- macOS (VST3 and Audio Unit)
============================================

Oh Derek is a synthesized drum machine by QUASI. This is the demo: the full instrument for
14 days, from the first time you load it. After that it makes no sound and tells you so;
the full version is at https://quasiaudio.com.

Runs on macOS 11 (Big Sur) or later, on Apple Silicon and Intel Macs, in any host that
loads VST3 or Audio Unit instruments (Logic Pro, Ableton Live, Bitwig, Reaper, Cubase, ...).

Install
  Copy "Oh Derek.vst3"      to  /Library/Audio/Plug-Ins/VST3/        (or ~/Library/Audio/Plug-Ins/VST3/)
  Copy "Oh Derek.component" to  /Library/Audio/Plug-Ins/Components/  (or ~/Library/Audio/Plug-Ins/Components/)
  Then restart your host and let it rescan its plug-ins. You only need the format your host uses.

If the host does not show it, or macOS says it "cannot be opened"
  These plug-ins are not notarized by Apple yet, so macOS may block them because they were
  downloaded from the internet. Open Terminal and run (for the folders you used above):

    xattr -dr com.apple.quarantine "/Library/Audio/Plug-Ins/VST3/Oh Derek.vst3"
    xattr -dr com.apple.quarantine "/Library/Audio/Plug-Ins/Components/Oh Derek.component"

  then restart the host. Logic Pro: if it still says the Audio Unit failed validation, run
    killall -9 AudioComponentRegistrar
  and open Logic again. Do this only if you downloaded Oh Derek from https://quasiaudio.com
  and trust the source.

Getting started
  Press PLAY (or start your host): the drums play their pattern. KIT picks one of the 16 factory
  kits; each lane's own sounds are under its preset name (bank Factory). GENERATOR makes a new
  kit and pattern from a style. The factory kits and presets are written on first load to
  ~/Library/Application Support/QUASI AUDIO/Oh Derek/Presets (your own files are never replaced).

The trial
  The panel shows how many days are left (the red TRIAL badge; click it to open quasiaudio.com).
  Your projects keep Oh Derek's settings as they are, so they open in the full version unchanged.
