Plugins behaving badly?

This section contains information to help bring wayward plugins back into line. Also see the section on optimizing performance and check to see you are using the latest plugin wrapper and shared files from our forums here.

Options and Settings

Target problems:

  • Spiking CPU meter, crashes, no sound, rendering quality, rendering sync (timing), loop-playback issues:
    • Open the plugin wrapper 'Processing' tab and select 'Use fixed size buffers'. If this is not successful proceed below.
    • Open the Audio Settings and try CPU options - 'Multithreaded generator processing' (try off), 'Multithreaded mixer processing' (try off) & 'Align tick lengths' (try on/off).

      NOTE: If 'Multithreaded processing' is the cause of problems, then permanently disable it for the plugin/s at fault. Do this by deselecting the Wrapper Additional Settings Menu 'Allow threaded processing' switch and saving the wrapper state. The options set will be remembered for that particular plugin next time it is opened. Enable the global, Audio settings, multithreaded processing options for the remaining plugins.

  • Sluggish Start/Stop or Playlist is glitchy - Try Audio Settings > Mixer > 'Reset plugins on transport', OFF.
  • MIDI, automation, GUI & patch-changing issues - Try the plugin wrapper 'Settings > GUI & Automation' options.
  • Known issues - Check the Knowledge Base article; Problems with VST / AU Plugins in FL and Solutions (Wrapper Settings) for plugin specific information.
  • FL Studio 32 vs 64 Bit - Make sure you are using a 32 Bit version of the plugin with FL Studio 32 Bit or the 64 Bit version of the plugin with FL Studio 64 Bit. It could be the bit-bridge wrapper that is crashing. If this solves the problem, please report the plugin to Tech Support so we can fix it.
NOTE: When you identify a problem with a plugin, even if one of the steps above fixes it, please contact the developer. If problems are not reported, they won't get fixed!.
