[Csnd] Midi to OSC and polyphony

Subject	[Csnd] Midi to OSC and polyphony
	I am trying to convert midi to OSC. It works well with single notes, but not with chords. The receiving end (a Pyo Python program) could receive OSC lists, but how do I generate these? My idea is to store the first note in an array, and add subsequent notes that arrive within a short time interval. Then send the array over OSC... Here's my code so far: ; Initialize the global variables. ksmps = 32 nchnls = 2 0dbfs = 1 massign 0,12 instr 12 mididefault 60, p3 midinoteoncps p4, p5 ikey init p4 iVel init p5 kDur timeinsts ; running total of duration of this note kRelease release ; sense when note is ending print ikey,iVel OSCsend 1, "localhost",8000, "/midi/non", "i", p4 OSCsend 1, "localhost",8000, "/midi/amp", "i", iVel if kRelease=1 then ; if note is about to end printk2 kDur OSCsend 1, "localhost",8000, "/midi/non", "i", p4 OSCsend 1, "localhost",8000, "/midi/amp", "i", 0 endif endin -- Sent from: http://csound.1045644.n5.nabble.com/Csound-General-f1093014.html Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here

	Hi, You oculd simplify it by sending all the parameters in one OSC message, like: OSCsend 1, "localhost",8000, "/midi/note", "ii", inote, ivel and you can keep on adding more values if you want. There is a slight overhead on sending OSC messages, so for large amounts of data, you could also bundle them https://csound.com/docs/manual/OSCbundle.html Oeyvind lør. 16. nov. 2019 kl. 09:20 skrev zappfinger <zappfinger@gmail.com>: I am trying to convert midi to OSC.
