Hi,

Is there any command to reset all OSC values to 0 ?

For example : i have a button on my ipad that a press when something is going wrong to have a full reset.

I tried reversing the problem, with the /lj/osc/sendMeAllMappedValues to get all the OSC values on my controls but i use OSC Router and i think the packet is to big to go trough

Error 10040 is Winsock's WSAEMSGSIZE — "message too long." It means LightJams is sending a single OSC UDP packet that's bigger than the receive buffer your OSC router has allocated for that socket, so the packet gets truncated/rejected on the way in.

This typically happens when LightJams bundles a large number of OSC messages into one OSC Bundle and fires it as a single UDP datagram — if that bundle exceeds your router's buffer size (many apps default to something small, like 1024 or 4096 bytes), you get exactly this error.

Hi,

I've added a limit to the number of messages per bundle when responding to the sendMeAllMappedValues request. You can download the latest beta v788 here: https://www.lightjams.com/app/lightjams64_test.msi. Hopefully, this will fix the receive problem.
