Integer data type

[smadds]

Like @nfavrod I am also trying to control a Behringer X32 with this node.

Some commands need the response defined as an integer - e.g.:
/ch/01/mix/on ,i 0

It seems to fail with the ,f number type. Is there any way to force the ,i prefix when outputting data from the OSC node?

[smadds]

I think I've found a partial answer to this, by sending a json payload to OSC in this format:
{"type":"i","value":0}

Yay - this works!, but I have yet to figure out how to send multiple values without OSC thinking it's a return message from the device. e.g. these both fail:
{"type":"si","value":"scene 0"}
{"type":"si","value":["scene", 0]}

Any ideas??

I am sorry it has taken so many months to respond. I don't seem to have received an email when this issue was created.

That Behringer X32 mixer looks like fun! Did you manage to get it to work?

JavaScript / JSON does not make a distinction between Floats and Integers and it looks like the osc.js library defaults to using floats. Some client implementations (eg. liblo) will auto cast a float to an integer if it is expecting an integer.

The syntax for sending both a string and an integer is:

[
  {
    "type": "s",
    "value": "scene"
  },
  {
    "type": "i",
    "value": 0
  }
]

This is documentation on this formatting in the osc.js README:
https://github.com/colinbdclark/osc.js

I just did some tests using Node-RED and oscdump and got the output:

ded9633a.358d25ed /foo/bar si "scene" 0

Hello and thanks for the nice plugin.
I can confirm the x32 accepts this format. Tested with
[ { "type": "s", "value": "/ch/01/mix/fader" }, { "type": "i", "value": 30 } ]
with topic /subscribe subscribes to value on first fader for the next 10 seconds (the integer limits the amount of messages the mixer sends back).

@terwarf : Thanks for the input!

Can you share maybe the node-red flow? I would be highly interested to see how you've set it up. I am trying to setup the following OSC command:

/load ,si scene 00

But I was unable to do that using the following flow:

Any thoughts?

@alexszilagyi I remember trying to switch scenes, but i couldn't get it to work.
So I gave up on this topic and stopped controlling the mixer with node-red.

If I remember correctly, i just used an injection node for the test mentioned above.
