Arne Scheffler has updated VSTKit, his framework for hosting VST3 plug-ins, to v0.7.0. This new version brings the framework up to-date, with using c++11 and objective-c ARC, while support for Carbon and 32-bit is removed.
- On the feature side there's now support for IPresentationLatency so that plug-ins (who support this) display their UI in sync with the sound.
- The VSTKit Test application now features MIDI learn for plug-ins that support the IParameterFinder interface.
- It registers itself with the system to handle the VST3 extension, so that when you double click a VST3 file in the Finder the application will open and instantiate the plug-in. If there are more than one plug-in inside the bundle it shows a selector window to choose from.
- A new preference dialog allows to specify the knob mode to use in the plug-in editors.
- Audio Engine and MIDI settings are also part of the dialog.
- In the MIDI settings tab you can define which MIDI port should be automatically connected to the first plug-in event bus instead of all as in previous versions.
- Finally Mac OS X fullscreen feature is supported and when loading a vstkit document the plug-in can query for IStreamAttributes on the plug-in state.
