Two function\n   nodes show the pattern: the first sets the OSC address (msg.topic), the\n   second sets the message (msg.payload). The OSC output node sends whatever\n   arrives.\n2) Live BPM: the Beat node emits once per beat while a deck is playing.\n   'Keep only BPM changes' remembers the last BPM and only lets a message\n   through when the value changed. 'Set the address' sends it to\n   /time-line/bpm.\n3) Test buttons: no deck playing? Click these to push a fake BPM through the\n   same chain.\n\nSETUP - YOUR OSC RECEIVER\nDouble-click an OSC output node, then click the pencil icon next to 'Server'\nto set host and port. This example points at 127.0.0.1:8000, which is where\nProtokol (a free OSC monitor by Hexler) listens - handy to see what arrives.\nPoint it at your lighting console / Resolume / TouchDesigner instead, and\nchange the address in 'Set the address' to whatever your show system expects.\n\nNOTES\n- The OSC output node uses its Address field first; when that is empty it\n  falls back to msg.topic. This flow sets msg.topic in a function node so you\n  can see the pattern.\n- BPM follows the pitch fader, so it can change often. Uncomment the rounding\n  line in 'Keep only BPM changes' to send at most 1 decimal.\n",
