Accessing BPM and time signature of Plug-In Host

I am working on an audio plugin and would like to map LFOs to various parameters. How does the plug-in access the DAW's BPM value and time signature?

Does the host need to expose this through VST or AU protocols or how should a plug-in access properties it needs during runtime?

Solution

  • For anyone with the same requirement, the JUCE library has an object called AudioPlayHead

    You can then get the current position info inside your processing callback

    audioPlayHead->getCurrentPosition(currentPositionInfo)

    and then access the BPM on the position info using currentPositionInfo.bpm
