Looks like I solved my own problem. Replace lines 700-711 from the original OSCClass.cpp (v1.0.1) with the code below. This will output the osc messages without the forward slashes.
if(adrCount<MAX_ADDRESS){
//Added this in to remove the slashes out of final output
if(d!='/'){
tempAddress[adrCount][adrMesPos]=d;
if(packetCount>3) {
packetCount=0;
packetPos+=4;
}
adrMesPos++;
}
}
messagePos++;
packetCount++;
