Serialosc/monome with Organelle?

Sorry I’m super lost. (almost ZERO linux/terminal understanding)
this nice guy responded me on the lines forum, but still no luck : https://llllllll.co/t/organelle-and-monome/1972/38

Sorted ! (ten characters)

From this message, how can you say that a bad formatted message is send to serialosc ? Doesn’t it just mean that a modulo object somewhere receives a symbol ?

EDIT :
ha !!!
I guess it’s because I’m sending it to a [s led] object, which is already used for the Organelle’s led !
