Steinberg updates VST Audio Plugins SDK to v3.6.12 (build 67)

Steinberg Media Technologies has updated the VST SDK to v3.6.12 (build 67).

A brief overview of changes:

• VSTGUI 4.7:
  • fix crash with splash screen.
  • fix compilation for VSTGUI Tools on win32.
• Interfaces Changes:
  • New Steinberg:Vst:LegacyMIDICCOutEvent: allowing a Plug-in to generate MIDI CC as output event.
  • New Steinberg:Vst:IMidiLearn (Plug-in): allow a Plug-in to get the currently live playing MIDI CC to implement custom MIDI learning.
  • New Steinberg:Vst:IPlugInterfaceSupport (Host): allow a Plug-in to ask the host if a given Plug-in interface is supported/used by the host.
  • New Steinberg:Vst:IVst3WrapperMPESupport (Wrapper): allow a Plug-in to setup MPE support in wrappers.
• cmake:
  • small refactoring (like renaming WIN to SMTG_WIN).
  • fix WIN_ARCHITECTURE_NAME for Windows 32-bits.
  • fix SMTG_PACKAGE_ICON_PATH selection.
  • split WIN_PDB into WIN_PDB32 and WIN_PDB64.
• Samples:
  • New LegacyMIDICCOut VST3 Plug-in showing the use of LegacyMIDICCOutEvent.
  • Add Steinberg:Vst:IMidiLearn support for NoteExpressionSynth.
  • Add Audio Unit v3 NoteExpressionSynth example with MPE support.
• Plug-in Wrappers:
  • Audio Unit v3 (AUv3) Wrapper:
    • out of the box MPE support. As MPE is a limited subset of the Note Expression feature, the three expressions are simply mapped to the note expressions returned via Steinberg:Vst:INoteExpressionPhysicalUIMapping interface.
    • note that you must have certificates to sign on macOS/iOS for AUv3.
    • complete folder restructuring for easy adaption.
  • AAX Wrapper:
    • fix automation update after loading a preset.
  • VST2 Wrapper:
    • fix double release of editor.
• Helpers Classes:
  • New file with some helpers for event: vsteventshelper.h.
