Generators in the channel rack and, later, effects in mixer slots are plugins. Their events follow the channel or slot that holds them.
Events
| ID | Size class | Name | Holds |
|---|---|---|---|
| 0xC9 (201) | Text | Plugin file name | The plugin’s file name “without path”. |
| 0xCB (203) | Text | Plugin name | The name shown to the user, used for mixer slots from version 3.3. |
| 0xD2 (210) | Data | TS404 parameters | The settings of the built-in TS404 synthesiser. |
| 0xD4 (212) | Data | New plugin | Settings of the wrapper that hosts the plugin. |
| 0xD5 (213) | Data | Plugin parameters | The plugin’s saved state. PyFLP dates it to 1.6.5. Its layout belongs to the plugin. |
PyFLP notes VST support in the wrapper from version 1.5.23.
Old wrapper data
An appendix to Image-Line’s document, added after 1999, describes the data of the Fruity Wrapper, which hosts third-party plugins. In its old format, used up to wrapper version 4, the data gives in turn the size of an extra block, the MIDI port, whether the synth state is saved, the plugin type, a block size and then the plugin’s name. Later wrapper versions switch to a list of chunks. Which FruityLoops versions write which wrapper version is not recorded.
