WebMidi recieveControlChange ?

[zodnik]

Hi I am very new to webMidi but have been trying to work out how to Recieve midi CC messages on channels 1-16 ect.
I have been able to addListener for pitchbend and also recieve CC messages
the addListner.midimessage returns 'channelcontrol' regardless if it's CC 1, 2 or any other so for example

mySynth.channels[1].addListener("midimessage", e => {
document.body.innerHTML+= ${e.message.type}
;
});
above returns 'channelcontrol' regardless of which CC is being sent to it.
Question is there a way to get it to detect individual CCs ? It sees 'pitchbend' are there any others?

const mySynth = WebMidi.inputs[0];
mySynth.channels[1].addListener("pitchbend", e => {
document.body.innerHTML+= ${"pitchbend" + e.value} <br>;
});

I found ways to control individual CC's via output
WebMidi.outputs[0].sendControlChange("volumecoarse", 54);

is there some way to track those individually via input? something like
WebMidi.inputs[0].recieveControlChange(volumecoarse.value);
or address them via CC number? thanks

You can add a listener for a specific control change message number (documentation here) :

const mySynth = WebMidi.inputs[0];
  mySynth.channels[1].addListener("controlchange-controller123", e => {
  document.body.innerHTML += e.subtype + "<br>";
});

Note that, when you listen to the generic "controlchange" event, the subtype property will tell you the name of the specific controller that triggered the event.
