hi,

i build a pure-data patch with the function of a multitrack audio player. to control this patch, i used the osc-extension. my problem is, that pure data ignores the first 4-10 messages, when the patch is fresh started.

does anybody know why? ... and how i can fix this problem?

best regards christoph

I doubt they're lost so much as buffered somewhere, but I'm no OSC expert.
Can you find a command to flush all the messages through?

hallo obiwannabe,

>>>Can you find a command to flush all the messages through?

i don't understand your question. the messages where sent by a programm written in c++.
they will definitly sent by this programm. only if the pure data patch is fresh started the first messages will be lost.

i tested it with this little patch:

[dumpOSC 3456]

[print]

thanx for the post

christoph

I had a similar problem with a C program I wrote using liblo. What solved it was waiting until Pd had finished loading before sending messages from my program, by having my Pd patch send an OSC message to my C program to say "I'm ready to receive data now".

OSC uses UDP by default, and Wikipedia says: "UDP does not provide the reliability and ordering guarantees that TCP does. Datagrams may arrive out of order or go missing without notice."
