RE:otudp problems

Hello!
I use :”Kroonde” la kitchen to control my patch, but I got an error message:
Otudp: Out of packet buffers; have to drop packet(S)
Thanks for any hints.

How about seq~? While two dimensions wouldn’t be enough to represent a
list, seq~ is a great help for looping control-rate events.

Did you try setting a larger number of buffers:

otudp read

nbufs 128 (I’m not sure what the default value is)
otudp read
nbufs 256
otudp read
nbufs 512
otudp read
nbufs 1024

etc…

otudp has problems when you are in overdrive. That’s the one time I
see this message, which tends to get worse over time, as you patch
runs. I imagine it has to do with the frequency of servicing otudp
when you are running MaxMSP processes in high and low priority
threads.

With overdrive off, really high data rates can cause this problem,
too, but it’s much less of an issue.
