Hi folks,

I'm building a 2 way system consisting of 2 way send and receive patches. One patch will send 8 vslider values to the other patch via OSC and udpsend, while the other patch receives these values, and on adjusting sliders here, can send back changed slider values once again through udpsend and OSC.

I'm getting an error saying "Packet size (5) is not a multiple of 4 bytes: dropping packet."

I understand that an OSC packet has to be 4 bytes long. So how do I do this?

OSC packets have to have a size that are a multiple of 4 (filling up with zeros if necessary), so instead of 5 bytes it should be 8 bytes.

[packOSC] will always generate correctly sized packets (at least it does for me). for whatever reasons you are loosing some bytes somewhere, try to find out where - could be a wrong usage of [udpsend], something on the network transport (statefull firewall, but unlikely), something you do after [udpreceive] before the [unpackOSC]...it's a bit hard to tell what is going wrong without a (stripped down) patch
