OwnAudioVST3 V1.4.5

v1.4.5 — April 2026

New Features

• MIDI-Only Plugin Support — Added IsMidiOnly property to detect MIDI-only plugins (e.g. MIDI effects, arpeggiators) without audio I/O. Added SendMidiEvent(status, data1, data2) convenience method as a shorthand for ProcessMidi.
• Actual Channel Count — Added ActualInputChannels and ActualOutputChannels properties that report the real channel configuration negotiated with the plugin at runtime.
• Tempo & Transport API — Added SetTempo(bpm), SetTransportState(isPlaying), and ResetTransportPosition() methods, enabling hosts to drive plugin transport and tempo synchronization.
• ProcessAudio Channel Guard — ProcessAudio() now validates channel counts against the plugin's actual configuration and silently bypasses processing on mismatch, preventing crashes from misconfigured buffers.

Bug Fixes

• Fixed setBusArrangements rename to align with the VST3 SDK API, resolving compatibility issues with certain plugins.
• Applied VST3 compatibility fixes from the native layer (submodule update to v1.4.0).

Infrastructure

• Upgraded target framework to .NET 10.0.
• All new native functions are loaded via TryGetDelegate for backwards compatibility with older native library versions.
• Updated native libraries.
