Changelog:
- Fixed MIDI tracks export that were missing the end-of-export tail parameter and bailing out always with default SMF format anyway.
- Fixed VST3 component/controller inter-connection.
- LV2 Atom/Port-event host notification support has been retouched, but still unofficial though.
- Fixed VST3 audio-processor initialization/activation when a plugin has no inputs or outputs present.
- Let main window use pseudo-asynchronous stabilization re. menus, tools and status bars, are just faster and immediate.
- Fixed MIDI track monitor reinstantiation and reset.
