Summary0000210: Two VST instruments not loading their parameters unless I click play or play a note

When loading .IT files, two VST instruments I have do not load their parameters unless I click play or if I manually play a note with the VST. They remain on the defaults the VSTs have when loaded into a song for the first time. That is, aurally. Visually, they appear to be set up just how I left them.
It is a problem when using Export as Wave, mainly, as Export as Wave does not cause the parameters to load.
Even if I do play a note or click play, it seems like they still start out from the initial settings, then they transition into the parameters I had set after a couple of seconds, whether it be something manually set up, or a preset.

I tend to close files and re-open them before exporting, to clear out any fading notes, etc. still in the audio buffer.

This problem happens with Rez v3.0
and SUPERWAVE P8 2.3 (2.3 is what it says in the corner in the actual VST, anyway)

Notably, SUPERWAVE P8 1.6 doesn't have this problem.

Steps To Reproduce
  1. Load an .IT using P8 2.3 or Rez 3.0, where they've been set to a preset other than the default one.
  2. File > Export as Wave, and export a wave.
  3. Notice in the resulting wav file that the VST instrument acted as if it was loaded into the song for the first time and not tweaked or set up at all.
Additional Information

This does not happen in Psycle (, 1.8.8 RC1), so I am unsure it is a VST bug.

TagsNo tags attached.
Has the bug occurred in previous versions?Also occurs in,, and haven't tried any interim versions
Tested code revision (in case you know it)

Strange issue, but so far I can't see why it happens. :\

As a workaround, you can assign the proper MIDI Program / Bank numbers to your mod instruments, so if a mod instrument is assigned to an P8 instance that should play P8's second patch, you'd set the MIDI Program of that mod instrument to 2. I think those plugins don't process program changes while they're suspended, but I'm not 100% sure yet.

I opened a related thread on KVRAudio, just for reference:

Ok revision 1230 / OpenMPT should fix it. Enjoy!

I did a quick try of P8 and Rez, and indeed, it is fixed.
