Hi there,

I keep exploring open stage control ([https://osc.ammd.net/)](https://osc.ammd.net/) to create a visual interface for Sonic Pi.

the doc concerning edit the interface in open stage control [https://osc.ammd.net/extras/remote-control/](https://osc.ammd.net/extras/remote-control/)

I need to send the osc message  
In python using the python-osc it works with this code

```ruby

"""
Test d'envoi vers open stage control d'un message osc
pour changer un label dynamiquement
"""
import argparse
import random
import time

import json

from pythonosc import osc_message_builder
from pythonosc import udp_client

"""
jsonData = '{"label":"New Label"}'
jsonToPython = json.loads(jsonData)
"""

pythonDictionary = {'label':'nouveau nom', 'color':'pink'}
dictionaryToJson = json.dumps(pythonDictionary)

if __name__ == " __main__":
  parser = argparse.ArgumentParser()
  parser.add_argument("--ip", default="127.0.0.1",
      help="adresse du serveur openstagecontrol")
  parser.add_argument("--port", type=int, default=8080,
      help="8080 the port is listening on")
  args = parser.parse_args()

  client = udp_client.SimpleUDPClient(args.ip, args.port)

client.send_message("/EDIT", ("push_4", dictionaryToJson))
time.sleep(4)
client.send_message("/EDIT", ("push_4", '{"label":"New Label"}'))

```

Now i need to make it work in Sonic Pi but i miss something about the syntax.

```ruby
live_loop :changeLabelPush_4 do
  options = {"label" => "depuis sonic pi"}
  require 'json'
  # => true
  options.to_json
  puts options
  osc_send "127.0.0.1",8080,"/EDIT", "push_4", options
  sleep 4
  stop
end

```

it give this in the sonic pi journal

```ruby
{run: 17, time: 4.0, thread: :live_loop_changeLabelPush_4}
 ├─ {"label"=>"depuis sonic pi"}
 └─ OSC -> 127.0.0.1, 8080, /EDIT, ["push_4", {"label"=>"depuis sonic pi"}]

```

and causes an error in the open stage control log

```ruby
OSC received: { address: '/EDIT', args: 'push_4' } From : 127.0.0.1:4560
[Renderer process error]
Uncaught SyntaxError: JSON5: invalid character 'u' at 1:1

at receiveOsc (src/browser/js/app/ipc/callbacks.js:17:12)
at require (src/browser/js/app/ipc/index.js:40:16)

```

Open stage control needs this

```ruby
OSC received: { address: '/EDIT',
args: ['push_4', '{"label":"New Label"}'] }

```

Some clever ideas to help ?  
Cheers

well i find the good syntax. May it helps.

```ruby
live_loop :changeLabelPush_4 do
 
 require 'json'
 options = { :label => "from sonic pi"}.to_json
 puts options
 osc_send "127.0.0.1",8080,"/EDIT", "push_4", options
 stop
 sleep 4  
end

```

I only used OSC with processing and haven’t sent OSC yet, but it seems to me that what SP is sending is what you want.  
From the error message I guess that the second argument is not recieved, possibly a type conversion error?
