## Hi How could you do that from python and using a push button, you play a note or chord of sonic pi This code is to turn on a LED (if it works):

import RPi.GPIO as GPIO  
import time

GPIO.setmode(GPIO.BCM)  
GPIO.setup(24, GPIO.IN, pull\_up\_down = GPIO.PUD\_UP)  
GPIO.setup(23, GPIO.OUT )

## while True: input\_state = GPIO.input(24) if input\_state == False: GPIO.output(23, True) # Enciende el LED print(‘Botón pulsado’) time.sleep(0.3) GPIO.output(23, False) # Apaga el LED

## and this plays a note from a python script (it also works):

from subprocess import call  
call([“sonic\_pi”, “play :E5”])

when i add this to the led code it doesn’t work  
Thanks for your attention  
thanks google translate xd

Hi @Fer, welcome!

I recommend using [OSC](https://sonic-pi.net/tutorial.html#section-12) to communicate the notes to play from Python to Sonic Pi. See this thread for an (similar) example and more detail: [Link sonic pi to Python](http://in-thread.sonic-pi.net/t/link-sonic-pi-to-python/2938/5)  
You can adapt that code to send note values and play them in Sonic Pi - let us know if you need more help.

hi @Fer

to display code into posts more friendly, puts code between `````
