catching events in web based csound (pnacl)

Subject	catching events in web based csound (pnacl)
	For my web based Music tutor program, I would like to catch midi events (a midi file being played) and show the notes on a javascript piano. My previous version of Music Tutor was stand alone, and required csound to be installed, OSC and python. I used OSC then as the 'glue' between midi events and the keyboard. What would be the best way to catch midi events in the pnacl based situation? I am considering web sockets, but I have to catch the midi notes first....

	Hi, I have never used it but I think Csound pnacl has MIDI support: http://vlazzarini.github.io/docs/pnacl_csound.html MIDIin(byte1, byte2, byte3) - sends a MIDI in message to Csound. NoteOn(channel,number,velocity) - sends a Note ON message to Csound. NoteOff(channel,number,velocity) - sends a Note OFF message to Csound. PolyAftertouch(channel,number,aftertouch) - sends a polyphonic aftertouch message to Csound. ControlChange(channel,control,amount) - sends a control change message to Csound. ProgramChange(channel,control) - sends a program change message to Csound. Aftertouch(channel,amount) - sends a mono aftertouch message to Csound. PitchBend(channel,fine,coarse) - sends a pitchbend message to Csound. For catching MIDI messages from the javascript side I think there is web midi api https://webaudio.github.io/web-midi-api/ Otherwise websockets is definitely good idea, now there is websocket opcode inside Csound. Hope it helps a bit further! tarmo On Saturday 16 January 2016 17:28:23 you wrote: > For my web based Music tutor program, I would like to catch midi events > (a midi file being played) and show the notes on a javascript piano. > My previous version of Music Tutor was stand alone, and required csound > to be installed, OSC and python. > I used OSC then as the 'glue' between midi events and the keyboard. > What would be the best way to catch midi events in the pnacl based > situation?

	Thank Tarmo, Yes we have web sockets now, forgot about that. My lessons are short midi files played by csound (and textual explanations) and the notes have to be animated on a GUI piano keyboard. So I guess csound websockets are my best option, provided they work in the pnacl environment....

	Hi, I am afraid they don't, in fact - as pnacl does not support csound plugins and websocket depends on libwebsockets library. But you can implement receiving websockets in the javascript side and foraward data via channels events as needed.

	Check this out. I think you could adapt this to use PNaCl fairly easily. https://github.com/qiao/euphony In fact, there are a lot of wonderful goodies here that would be useful with PNaCl, csound.node, Csound for Android, CsoundQt, or any other system that allows you to call the Csound API using JavaScript. It should be possible to embed MIDI files directly in Web pages, create a piano roll viewer for Csound scores, play an on-screen 3D piano keyboard, etc., etc. Regards, Mike ----------------------------------------------------- Michael Gogins Irreducible Productions http://michaelgogins.tumblr.com Michael dot Gogins at gmail dot com On Sat, Jan 16, 2016 at 3:03 PM, Richard wrote: > Csound is playing the midi files in pnacl with a GM soundfont.

Subject	Re: catching events in web based csound (pnacl)
	This seems to work, see my code snippet below. In the 'loop' part (handleMessage) I use csound.RequestChannel, and then filter on the message received. But, If I understand it correcly, this lags one cycle behind: the RequestChannel only has effect the next time the function handleMessage is called? Richard function filter(msg, filt) { var found = false; var sval = ''; var x = "::control::" + filt + ":"; if (msg.data.substring(0, x.length) === x) { sval = (msg.data.replace(x,'')); found = true } return {found:found, sval:sval}; } function handleMessage(message) { csound.RequestChannel("volume"); var ret = filter(message, "volume"); if (ret.found == true) { console.log(ret.sval); } else { // normal message handling ...

Subject	Re: catching events in web based csound (pnacl)

The alternative is to read the midifile in JS and send midi RT events to Csound. ======================== Dr Victor Lazzarini Dean of Arts, Celtic Studies and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 > On 17 Jan 2016, at 12:38, Richard wrote: > > Well, the code is based on your midiplayer.html.
