Hello

Is there a way to loop something while I press it? I want a volume up button that keeps going up untill I release the button.

Thanks in advance

I'm unable to use , /, or ' as valid targets for a TAP or PRESS command. I believe this is because these characters are considered "special" and require escaping in order to use them as plain characters.

Upon checking in pynput using a short script you can see what pynput sees when you type a backslash:

from pynput import keyboard

def on_press(key):
... try:
... print('alphanumeric key {0} pressed'.format(
... key.char))
... except AttributeError:
... print('special key {0} pressed'.format(
... key))
...
def on_release(key):
... print('{0} released'.format(
... key))
... if key == keyboard.Key.esc:
... # Stop listener
... return False
...

Collect events until released

... with keyboard.Listener(
... on_press=on_press,
... on_release=on_release) as listener:
... listener.join()
...
Key.enter released
alphanumeric key \ pressed
'\' released
alphanumeric key \ pressed
'\' released

Note the escaped version of the backslash: '\'.

Is there any option to autostart LPHK on PC boot load a config/layout and run it in the Background
Is there anything planed for the future?

Does this work with the Launchpad Mini mk3?

If you edit the file and add @LOAD_LAYOUT fake.lpl (make sure the file does not exist) the program will hold all command executions even after you have selected new layout and loaded your old layout

I cloned this on my mac. Python 3.6 in a virtual environment. Installed the dependencies, and then ran the script as in the instructions and get this error trace.

@nimaid, Now that I've got the hang of how to use this, would you be open to a PR with some more user friendly instructions when I have the time?

Ive tried to do this myself but im still a newbie to this sort of programming. Just thought id let you know I coulnt get this to work.

Hi,

The script recognize my genuine novation launchpad as a launchpad pro, therefore I'm unable to connect the launchpad to this script. Any ideas?

I use a MidiFighter3D, but this is undetected with it.

Hi!
I assigned simple buttons to the launchpad.
I want to use it with the game Elite: Dangerous.

If I press the assigned keyboard shortcuts on the Launchpad in a note, then I get the result directly. This means that the inputs via the launchpad actually work like a keyboard.

However, this does not work in the game.
The game does not accept any buttons from the launchpad.

Am I missing something here?

I have my novation launchpad MK2 plugged into my galliumos linux laptop, and for some reason, it can't be detected. here is the log:

Any help is appreciated. Thank you.

The basic steps to the error where:

1. Installing using the beta installer
2. Changing the env to the LPHK env
3. Running LPHK.py (with plugged in launchpad)
4. Loading the default example layout

The following error occurs when i press the left, light up and down keys:

Hooked up my LP Mini and tried to connect but connection failed after many redetects.

i have only 15 colors to choose from and dont know how to get the color spectrum?
can someone help?

If I use SOUND, the sound file's pitch is lowered when it is played. And plus how can i toggle keys by commands? I want to toggle Q key(i'll use autohotkey as ctrl+F23 as there isn't q in LPHK) for voice chat in games, but I don't know how. By the way is toggling keys is supported?

+) plz make toggling lights

@nimaid
OS: Ubuntu 18.04, fresh install. (Remember this)
PC: Thinkpad T430, i5 3320m, 16GB RAM, Samsung 256GB SSD
LP: LP MKII
Issue: I run the installer, it installs Conda fine. But when it tries to install LPHK, it doesn't create directories in ~/.conda and bitches to me that I don't have write permissions. I run as root, same issue. I run chown lyiriyah .conda. Still bitches. So I create the directories, change the ownership to me and run it again. It completes successfully. I run RUN.bash and it loads and doesn't detect my Launchpad. Happy fun. I am installing Conda myself as I write this, maybe that will change something.

While testing the program out on windows I noticed that the key commands like TAP, PRESS and @SIMPLE are only executed for the window that is currently focussed, this breaks using LPHK for stuff like controlling obs while you are streaming

Add the function to have a button to switch to another profile, or have the ability to open the profile with open file ability and load it up that way. I would love to have my right circular keys as buttons for 8 different profiles.

So currently I'm trying to bind vrchat gestures to my launchpad, these keybinds are:
shift+f1 through 8 for left hand
right shift+f1 through 8 for right hand

left hand works like a dream with the code:

PRESS shift
PRESS f1
WAIT_UNPRESSED
RELEASE shift
RELEASE f1

right hand however cannot be bound since when i replace shift with shift_r it comes up with an error message saying the key does not exist.

Error
AttributeError: module 'launchpad_py' has no attribute 'LaunchpadMk3'

Solution
Need to change the launchpad_connector.py file for the below:

Please notice that the class "LaunchpadMk3()" was renamed to "LaunchpadMiniMk3()" in 5/2020.

Currently investigating this issue, will update this issue when I have more info
pyautogui could possibly fix this issue ( #11 (comment) )

The is a typo in the shutting down function.
Wanted to commit a branch for it but that doesn't seem possible so here's the typo

Line 50 :
sys.exit("[LPHK] Sutting down...") -> sys.exit("[LPHK] Shutting down...")

Script:

PRESS win
PRESS shift
TAP right
RELEASE shift
RELEASE win

Expected behavior from JS Key tracker (https://unixpapa.com/js/testkey.html):

keydown  keyCode=91  ([)   which=91  ([)   charCode=0        
keydown  keyCode=16        which=16        charCode=0        
keyup    keyCode=39  (')   which=39  (')   charCode=0        
keyup    keyCode=16        which=16        charCode=0        
keyup    keyCode=91  ([)   which=91  ([)   charCode=0        

91 is win, 16 is shift and 39 is right arrow

Actual behavior:

keydown  keyCode=91  ([)   which=91  ([)   charCode=0        
keydown  keyCode=16        which=16        charCode=0        
keyup    keyCode=16        which=16        charCode=0        
keyup    keyCode=39  (')   which=39  (')   charCode=0        
keydown  keyCode=16        which=16        charCode=0        
keyup    keyCode=16        which=16        charCode=0        
keyup    keyCode=91  ([)   which=91  ([)   charCode=0  

Notice the 2 extra lines at line 3 and 5. I've tried variants of PRESS, TAP, ASYNC to no avail.

Edit: I'm using the Launchpad Pro (but other shortcuts seem to work fine, for example this script works fine:

PRESS ctrl
PRESS shift
TAP n
RELEASE shift
RELEASE ctrl

DELAY 0.5

PRESS ctrl
TAP k
TAP o
RELEASE ctrl

Hello everyone,
The idea is to have a main script that at a fixed point (startup) wuold read all files in a sub-folder (/commands) and if the file has the right format (normal .py script + a specific header) it would import it as an available command/function in the LPHK language.

The script will check for the libs that it needs to run that specific script and install it via pip.

In the header, there will be a way to rename functions.
When using an importend function you need to use the name of the file "x" and the name of the function "y".
In the LPHK script, you will need to write x.y as a command.
When importing a file, the script will create a dictionary and associate a specific command with a custom name.
Something like function['WEB_NEW']=Web.open_ new.
Thanks to this, you'll be able to use the custon name and make the LPHK script look "nicer".

I'm having issues to get the mouse coordinates of where I want it to click.

This issue could be solved by adding a command to LPHK Script, that displays the current mouse coordinates somewhere.

As an example:
M_COORD would show the current coordinates of the mouse in a pop-up window

If you could add this command, it would really help me programming my macro keys.

I absolutely love the concept of LPHK, but I only own a Launchpad Mini. Is it possible you can work towards a solution for Launchpad Mini? And if so, could I request a rough estimate on when I could use LPHK with Mini?
Thanks in advance.

Edit: I apologise, I had not read the readme thoroughly.

I tried to set up a button to lock my computer using the key combination Windows + L.
The Code I used looks like this:
PRESS windows
TAP l
RELEASE windows
However it didn't do anything, but when I used a combination like Win + E (for opening a file explorer) it worked just fine...

regardless of a .wav file I used or one of the examples it stills shows that the file cannot be found.

Hi @nimaid

I was wondering if there is a way to map numeric keys.
If i do a @simple 4, the 4 on the normal keyboard will be pressed, but I can find the way to press 4 on the numeric block of the keyboard.

Best regards
Rasti

Hi,
I have an idea :
Make a function to change layout when you click on a button.
They can be good to have multiple board and easy to change layout.

(sorry for my english, i'm french)
great project

Any way to make it so i can key in to load certain layouts on button press so i can switch between layouts faster?

Hey !
When i use the "STRING" argument, i can't use accents like:
"STRING é". The "é" simply not appear :/

(sorry for my english, i'm french)

Thanks,
Mathitux

Hi!
Firtst of all, thank you ever so much for this project! I really appreciate this 👍

Is there a function which allows for the command to repeat while the button is pressed?
For instance with vol_down.

While button is pushed down, repeat @simple vol_down until button is released.

Makes sense?

I am putting a mp3 sound into the examples file and using this code:
SOUND examples\meme.mp3
Keep getting a error message saying that it can not be found.
I have the default wav files in there and they work fine with the:
SOUND examples\airhorn.wav
And it is in the exact same file location.

Okay, I get this isn't about your software but it still baffles me. When I open pip.exe, it opens, and closes immediately.

Hi it would be nice if you could make it so that the sound could be played out of multiple outputs. so for example one through my headphones and one thorugh my mic (so that it would be an actual soundboard)

Today i made a layout to play fortnite with my launchpad mini and i had two problems:

I assigned "TAP d" to a key and when i ran it... it muted the sound of the computer;
I assigned "TAP g" to another key and it started playing music in spotify.

I once tested this and i had no problems.

My OS: Windows 10

When I try to use TAP/PRESS mouse_left/mouse_right it shows following error:

Can you allow parameters for OPEN? I like to start serialsend.exe and give lots of info to the program. At the moment I get error, file not found.

I've been using the application for a month now. And everytime I boot up, I need to launch the app, press the Live Mode pop-up for Launchpad Pro and then proceed to load my layout. I was thinking maybe there is a way to automate this, or even just load the last opened layout on the next boot.

Hi Ella,

I wanted to try out LPHK with my Launchpad Pro, with a custom firmware installed on it (https://github.com/mat1jaczyyy/lpp-performance-cfw) and when I try to launch LPHK, it recognizes my LP as a Launchpad Classic/Mini/S and first of all, the layout is all messed up and the buttons don't do anything. I'm also encountering this error when first starting LPHK.
Exception in thread Thread-2: Traceback (most recent call last): File "D:\Programmi\Miniconda3\envs\LPHK\lib\threading.py", line 926, in _bootstrap_inner self.run() File "D:\Programmi\Miniconda3\envs\LPHK\lib\threading.py", line 1177, in run self.function(*self.args, **self.kwargs) File "D:\Git Repositories\LPHK-master\lp_events.py", line 28, in run pressed[x][y] = False IndexError: list index out of range

I don't know what to do about it.

If you hold down a button with a simple script (no delay , @ASYNC or wait_unpressed etc) it will keep flashing until you release the button.
