[Recently I was asked](http://in-thread.sonic-pi.net/t/working-with-osc-as-variables/2840/10) about controlling various features of a running sample using OSC. This program and an associated article and video is the result.

Awesome project. Is it possible to make a generalized example for only receiving OSC messages.  
Because I’m confused about the sending part that are involved and its becomes very specific the example.

I just have continuous data coming in from an ESP wifi module and I need to set a variable set for each incoming osc signal. It must be easier not?  
😪🥵

Here is a simpler system which receives inputs from two separate sources via OSC  
The received data is stored using set commands and is then available for a separate live loop to do whatever you want with it. To test, I am generating the OSC messages locally in Sonic Pi, but they can come externally from your ESP8266, in which case you miss out (or comment out) the local section.

```ruby
use_osc "localhost",4559 # used only for local testing where SP creates the data.
use_debug false
use_osc_logging false

live_loop :var1 do #receive and store var1 data
  v1 = sync "/osc/test/var1"
  set :v1,v1[0] # store the received data
end

live_loop :var2 do
  v2 = sync "/osc/test/var2" #receive and store var2 datga
  set :v2,v2[0] #store the second variable value
end

#as many as you need like the above

live_loop :latestData do #independent live loop processes latest available data
  puts "latest values var1 #{get(:v1)} var2 #{get(:v2)}"
  synth :tri,note: get(:v1),release: 0.4 #first variable adjust pitch
  synth :saw,note: get(:v2),release: 0.4 #second variable adjusts pitch
  sleep 0.4 #latest values read every 0.4 beats
end

#local generation of test osc messages
live_loop :createData1 do
  osc "/test/var1",rrand_i(60,72)
  sleep 0.2
end
live_loop :createData2 do
  osc "/test/var2",rrand_i(72,84)
  sleep 0.6
end

```

The two test data streams run at different rates, so you can hear the two variables updating at different times not synced to each other. Depending on how rapid a response you need, you may require to add use\_real\_time.

AMAZING! IT WORKS PERFECTLY AND I CAN CHANGE EVERYTHING OR ADD STUFF EASILY!

Sorry about the caps lock but I needed to do that!
