Simple system call binding for Novation Launchpad
Uses FMMT666's launchpad_py to interface with the launchpad. At the moment it's hardcoded to use the Mk2.
At this stage just git clone the repo and run the python file
You will probably need to pip install pygame launchpad_py
./launchpad_binder.py --bindings-file <file>I wanted to keep it super simple - you can keybind up and down events. There is a very limited set of built in commands, everything that doesn't match these will be ran as a system call.
You can start with a basic confguration of:
{
"bindings": {
"88": {"down_command": "quit", "color": "10"},
"87": {"down_command": "record", "color": "20"},
"85": {"down_command": "save", "color": "30"}
}
}| command | :meaning |
|---|---|
| record | records a new keybinding |
| save | saves the current bindings into the file provided |
| quit | closes the binder |
| load | loads the json file provided and starts a new binding instance |
Pressing record puts the binder in record mode, the next key pushed is the key that it will bind. You will then be prompted for:
- Key Down action (can be left empty)
- Key Up action (can be left empty)
- A set of colors will show on the launchpad and you choose a color by pushing the corresponding button. (You can page right or left with the left or right arrow at the top)
saving will write all of the currently loaded bindings into the file that was provided when the launchpad-binder was executed
Load can be configured in two ways, when a up_command is provided it will override the key in the loaded file to perform the provided up_command. This is great for using a key as a modifier, for example, press key x, it loads the alternate bindings and when key x is released it will quit the binder, reverting to the previously loaded bindings file. Alternatively with no up_command provided, the binding will stay in place until a key with a quit command is used.
LPHK is different in that it provides a GUI, along with a custom scripting language
