Adds a per-destination "Max Rate (Hz)" field that caps how often a route emits OSC messages. Coalesce semantics: when input arrives faster than the configured rate, only the most recent message survives the period and is emitted at the next interval boundary; nothing is sent during silence. Useful for streaming sources (PSN, ArtNet/sACN-driven OSC bridges) where the input rate can saturate downstream consoles. Scope: OSC outputs only. sACN, ArtNet, MIDI, OTP, and PSN destinations are unaffected. Default 0 = unlimited; existing configs are unchanged. Refactor: per-destination dispatch in ProcessRecvPacket extracted into DispatchBuiltPacket, which returns whether a real send happened so the rate-limit timer only advances on actual sends. The flush pass runs once per main loop iteration after the TCP-clients section.

@MizPlusPlus This code is 99% written with AI and while I've looked it over and tested it, I haven't written any C since college. If the code is helpful, great. If it's not, I hope the framework for the features might be. |

Adds a per-destination Max Rate (Hz) field to each route. When set, the route emits at most N OSC messages per second to that destination.
Behavior
Implementation
ProcessRecvPacketwas extracted intoDispatchBuiltPacket, which returns whether a real send happened. Both the immediate-send path and the deferred-flush path go through it.FlushPendingRateLimitedruns once per main loop iteration after the TCP-clients section and emits any pending coalesced packets whose period has elapsed..osc.txt(maxRateHz). Old configs load unchanged; new configs round-trip.Notes
