I’ve encountered a couple issues while working with JUCE 4.2 to host VST3 plugins. 1. I can use the getNumPrograms() and getProgramName() functions successfully, but setCurrentProgram() doesn’t do anything. This isn’t surprising, given the function definition: I know VST3 uses “Program Lists” but I haven’t located any alternative functions for loading presets. Could anyone help me understand how to load a VST3 factory preset using JUCE? 1. I’ve noticed that calling reset() on a VST3 does not cause the plugin to flush its buffers as expected. Is there a mechanism in Juce’s VST3 implementation that can be used to flush the buffers of a VST3 plugin? Thanks! Dan ---

Hi SynthDan, Can you check the latest tip on develop to see if this is fixed? In particular can you check the following two commits: [Call setProcessing (false) when resting a VST3 plug-in](https://github.com/julianstorer/JUCE/commit/93a41cf7432e615fdb4c635ed01cfb2f7e4ef4a5) [Support factory programs in VST3 hosting](https://github.com/julianstorer/JUCE/commit/f4086ad8f4dc89dea296a6bb14df06bf123fbd78) Thank you!

All indications are that both of these issues are fixed beautifully. Thank you! Dan ---

It seems AudioUnits are still missing a `reset()` implementation it looks like i’d be enough to call `resetBusses()` or maybe even better `AudioUnitReset (audioUnit, kAudioUnitScope_Global, 0)`. Also hosted VSTv2 don’t seem to receive the `reset()` call. ---

I’d like to raise attention to this thread again. Maybe i should have started a new one? ---

Hi Luzifer, I’m aware of this bug. Sorry it’s taking so long but I will roll out a bunch of fixes for related issues with the multibus updates. ---
