Can't set custom variable from OSC remote

[yrphilippe]

Hello everyone,
I'm trying to modify the value of a custom variable in OSC with the command
/custom-variable/<name> <value>
but without success.
Moreover, nothing appears in the Log tab.
However, if I try other commands like :
/press/bank// <1>
it works
Do you have a suggestion?
Thanks
Yann
