TROUBLESHOOTING

Plugins behaving badly?

This section contains information to help bring wayward plugins back into line. Symptoms include issues like clicks, pops or crackling sounds but your underrun count isn't increasing (if it is click here. NOTE: Some ASIO options bypass the underrun counter so check). Plugins that play or render out of time with the timeline. CPU spikes, FL Studio lockups, crashes or rendering failures. There are three main places you can try making changes to settings and options to resolve issues with misbehaving plugins, they are:

Options and Settings

• Install the latest plugin wrapper from our forums here. The wrapper is the interface between FL Studio and plugins, it provides VST/VSTi 1, 2 & 3 (32 & 64 Bit) support.
• Open the Audio Settings and try the following:
  • CPU options - 'Multithreaded generator processing' (try off), 'Multithreaded mixer processing' (try off) & 'Align tick lengths' (try on/off).

    NOTE: If the Audio settings 'Multithreaded processing' options appear to be the cause of problems, isolate the plugin/s that are behaving badly 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, allowing you to turn the Audio settings multithreaded processing options back on (if desired).

  • Mixer options - 'Reset plugins on transport' (try turning off, if start/stop and moving around the Playlist is glitchy/slow).
  • ASIO4ALL - If you are using ASIO4ALL and getting crackling/glitches and the underrun count isn't increasing, check the Troubleshooting section of the ASIO4ALL settings.
• The plugin wrapper 'Processing' tab. Try these settings to fix problems with spiking CPU load, crashes, no sound, rendering quality, loop-playback behavior and rendering sync (timing issues). Start with 'Use fixed size buffers' then try the other options if that is not successful.
• The plugin wrapper 'Settings' tab. Try these settings to fix problems with MIDI, automation, GUI & patch-changing.
