touchOsc "multi" controls

Hi, dipping my toes into osc for the first time and reached the first hurdle.

The basics seem pretty straight forward and things are working as expected. However, TouchOSC has “multi” controls where a group of faders or buttons can be added and addressed as a single entity appended with a number to target the individual controls therein, using /1 /2 /3 etc. GP won’t accept the “/” and this is where I’m stuck. I noticed by accident that it does accept “_” but it doesn’t seem to work as an alternative.

hoping someone can shed some light.

Are you on Mac?

Are you using OSC together with GPScript?
