If you find after exporting a track from FL Studio (FAST plugin applied) the result sounds different to what you expected, please enable the Use fixed size buffers option in the plugin settings. This option can be useful in fixing rendering errors (glitching/timing issues) or crashes.
FL Studio shares data with plugins using variable sized chunks of data (buffers). Some plugins require fixed sized buffers (please see the FL Studio online manual for more).
To enable the Use fixed size buffers option:
1.) Open the plugin.
2.) Click the settings icon in the top left corner.
3.) Open the troubleshooting menu.
4.) Enable Use fixed size buffers.
