Windows: Korg Opsix Native settings lost on reload

Settings for Korg’s Opsix Native plugin don’t appear to save/load correctly with Renoise. A single instance can be used without any problems. Adding a second causes the settings to be scrambled on reload.

Example test:

  • New song.
  • Opsix as instrument 0, change preset to 1.
  • Save/reload - fine.
  • Opsix as instrument 1, change preset to 2.
  • Save/reload - both instruments sound like simple sine waves and have motion+sequencer turned on. The preset names are displayed correctly, so it’s not as simple as the wrong preset being loaded.

The same results were seen with Renoise versions 3.4.0 and 3.4.2. Opsix works fine with multiple instances in Reaper.
