fl_param_checker

A tool to help find plugin parameter indexes to assist with MIDI Controller Script development.

Installation

To install this as a standalone script, use the following instructions.

1. Download and copy this entire project to your Image-Line/FL Studio/Settings/Hardware folder.

2. Restart FL Studio, then in the MIDI settings, assign a free MIDI device to the "Param Checker" device. Ensure that the device has an input and output port assigned.

Integrating with your own device

To include this code within your own script, use the following instructions.

1. If you're using Git, add this as a git submodule. $ git submodule add git@github.com:MaddyGuthridge/fl_param_checker.git [output folder]/fl_param_checker

   Otherwise, copy this entire folder into your code (make sure to include the LICENSE file).

2. Ensure that the module's idleCallback() function is called during your script's OnIdle code somewhere.

3. Optionally, import the pluginParamCheck() function to your main device_*.py file so that it can be easily called from FL Studio's script output window.

Usage

1. Open the script output window, and call the pluginParamCheck() function with the index of the plugin you wish to inspect. For example, to inspect the first generator on the channel rack, call pluginParamCheck(0), or to inspect the first slot of the first (non-master) mixer track, call pluginParamCheck(1, 0).

2. Tweak the plugin parameter you wish to find the info on.

3. The parameter index will be printed. If multiple values change (eg if the plugin links more than one parameter together), all of them will be printed.

4. Repeat as necessary.

It is also possible to listen for parameter tweaks infinitely, by specifying the keep_alive parameter as True. If the checker is listening indefinitely, it can be stopped by calling pluginParamCheck() with no arguments.

Known Issues

Closing FL Studio or reloading the script while it is listening for parameter tweaks will cause FL Studio to freeze. It eventually does start responding again, but only after a minute or so depending on how long you've been listening for changes for.
