@jbaker Just a little more info that might help, although you might already have everything that you need.
Anything in the string /x/y/z/etc is part of the osc header.... the address.
The data that follows..... that is then sent to that address.... /x/y/z <space> data ..... is the part that needs to be specified as i, f, s, b
The address string should always be comprised of symbols (even though parts may "seem" to be integers or floats) and problems can arise using vanilla [oscparse] when they are not..... so [fudiparse] and [fudiformat] can solve that problem as demonstrated here...... vanilla_bug_oscparse_solution.pd
Unfortunately quite a few devices send malformed osc headers.
MrPeach objects don't care.
David.
