do not have Reaktor examples, but if you know Reaktor fairly well I can hopefully explain how you can interface with serialosc.
This is the main reference document for serialosc: https://monome.org/docs/osc/
If you want to skip autodetection, (on MacOS) find your port number manually by looking at the file inside the folder ~/Library/Preferences/org.monome.serialosc/
It’ll look something like this:
server {
port = 11451
}
application {
osc_prefix = "/example"
host = "127.0.0.1"
port = 13288
}
device {
rotation = 0
}
Make an OSC output that sends to localhost at port 11451.
Make an OSC input that receives on port 11111 (this is arbitrary but must be consistent)
Send this message to the OSC output:
/sys/port 111111
/sys/prefix grid
Now when you push grid keys you should be receiving messages on the input OSC port.
To light up a key use messages like:
/grid/led/set 1 2 15
(this turns on LED at x=1 y=2 brightness=15)
