Hm yes, good point. I've found another solution that works for now.
The problem I had is that I'm routing the OSC messages from Resolume through a Processing sketch, towards 2 other addresses (touchOSC and Duration.cc) - I was simply forwarding a message each time the oscEvent() listener was called - a listener for individual messages -, which resulted in a very large quantity of messages being sent one by one (due to the large number of animated params). TouchOSC became extremely unresponsive as a result.
My current fix is to create a bundle with an arbitrarily defined size. I haven't figured out a way yet to let my script detect when an entire batch has come in (this might be due to limitations of the OSCp5 library) so that I can recreate the bundles that Resolume is sending
And also, I'm just a shabby DIY programmer
