'This article lists VST plugins with known problems in FL Studio, and the solution (if possible).

The list is not complete, but we add toublesome plugins as we find them.
If you have a plugin that you fixed a problem for, not listed here, please report it in the Technical Support Forum. Just let us know to add it to the Knowledge Base.


If you are having trouble with a plugin and the solution is not here there is a section in the Manual - Plugins behaving badly that has tips on trouble-shooting plugins.

First, always start by downloading the latest version of the plugin from the developer and the latest version of FL Studio available to you.


Plugins with known problems in FL Studio are...

Bandstand

Turn on "Notify about rendering mode"

Chorus CH-2

Problem: no sound and the audio monitor shows a single line at the extreme left or right
Solution: switch on "
Use fixed size buffers" option in the wrapper (you'll have to reset/reload the plugin for it to take effect)

East West

Problem: strange noises and glitches while being played.
Solution: turn on "Use fixed size buffers" option in the wrapper

Emulator X3
Problem: crashes or produces no sound
Solution: turn off "Ultra-High Precision Interpolation" in Emulator X3

Hypersonic 2

Problem: the DXi version of this plugin doesn't work very well in FL Studio
Solution: use the VSTi version (from Channel > Add one > More, scroll down to the VST section)


Melodyne editor

Problem: playback position isn't correct in some cases
Solution: switch off the option "Send loop position" in the wrapper
Note: this workaround is not necessary in FL Studio FL 9.0.3 or higher
