How to Control CasterSoundboard with Python 3

Steps to send a one-way message

Install python-osc from the command-line (requires python3):

pip3 install python-osc

Open up CasterSoundboard
Create a new tab called test *
Add a sound to the 1 key *
Open the OSC settings dialog by pressing the button**
Click Start
Close the conformation window
Open a Python 3 interpreter by invoking one from the command line:

python3

Import pythonosc and initialise the client:

>>> from pythonosc import udp_client

>>> client = udp_client.SimpleUDPClient('127.0.0.1', 5051)

Play the clip we added:

>>> client.send_message('/castersoundboard/board/test/player/1/modify/play_state/play', 1)

* You don't need to follow these steps exactly, you'll just have to adapt some of the later steps if you pick your own names/keys.

** It doesn't really matter when you do this step, as long as you do it before trying to talk OSC to CasterSoundboard!

Example script using two-way communication

This script is from a gist, the raw text can be downloaded here.

For this to work, you'll need to set the Outbound Traffic client IP address to 127.0.0.1 in the OSC settings dialog in CasterSoundboard. Save the script as a Python file like csb_osc_comms.py then run it with python3 csb_osc_comms.py. When running, it will print any OSC message sent by CasterSoundoard as well as send a start/stop command to an associated player when you press a key on your keyboard. Send a . to quit the program.
