Metatarsals:
If you look at the name of this particular section of the forum, MaxMSP is in the title.
I can't see it.
If you've had to google it, you've wasted your own time.
That is not a nice attitude.
Lot's of people may be well able to help even though (like me) they know nothing about MaxMSP because lots of computer problems are much the same when you look under the hood. Serial data is serial data regardless of what produces it or uses it. Petrol (gasoline) is much the same whether it drives a Rolls Royce saloon or an off-road motor-bike.
So maybe have another think and, if you really want help, provide a full explanation of the problem.
