MIDI Events not working properly on most plugins

[dylanrenwick]

I'm working on a barebones VST Host, and I've noticed that, after setting up VST.NET and NAudio (using NAudio to handle MIDI data and Audio output), MIDI events are not working correctly on any of my 64bit Plugins except for Serum.

On Image-Line plugins such as Harmor and Sytrus, there is a buzzing note that plays while a midi key is held down, assuming the plugin is already outputting audio. The buzzing note is always F4 regardless of the MIDI note or plugin's note being played.

In FabFilter One, no sound is given
In FabFilter Twin 2, a very very short saw is played

I have tried bypassing NAudio completely and sending note number and velocity directly, I have tried altering the Note length being passed to VstMidiEvent, I have tried altering the NoteOffVelocity being passed as well, both to no effect.

I also managed to reproduce this same issue using perivar's MidiVstTest project, which also uses NAudio and VST.NET

I can only assume this is due to Midi Events being sent in some format that most VSTs do not support.

Nevermind, fixed the issue with all ImageLine plugins by simply writing a proper implementation for GetTimeInfo()
