I try to set midichannel the way i did set midiprogram, i get no complains but it does not change the midichannel on my module?

Is midichannel something that need to be sent with each note?

function changeMidiChannel(){
console.log("Change MIDI channel");
channelC=document.getElementById("out_channel").selectedIndex+1;
console.log("channel ",channelC);
if (channelC==1) {sysexC=0xC0}
else if (channelC==1) {sysexC=0xC0}
else if (channelC==2) {sysexC=0xC1}
else if (channelC==3) {sysexC=0xC2}
else if (channelC==4) {sysexC=0xC3}
else if (channelC==5) {sysexC=0xC4}
else if (channelC==6) {sysexC=0xC5}
else if (channelC==7) {sysexC=0xC6}

else if (channelC==13) {sysexC=0xCC}
else if (channelC==14) {sysexC=0xCD}
else if (channelC==15) {sysexC=0xCE}
else if (channelC==15) {sysexC=0xCF}
else if (channelC==15) {sysexC=0xD0}
output = mid.outputs.get(outportindex);
console.log("Channel ",sysexC," program ",programC);
var programChange = [sysexC,programC];
output.send( programChange );

This function work to set program via a input text field, and it basicly the same code as the midichannel change, except i type in program 1-128 instead of using select option list.

Probably my message to set midichannel miss some parameter, or have a bad format?

function changeProgram(){
console.log("Change program");
sysexC=0xC0;
programC=document.getElementById("prog_sel").value;
output = mid.outputs.get(outportindex);
var programChange = [sysexC,programC];
output.send( programChange );  
}

I think it could be a mismatch parameter because this table seem to say that each note must be sent with a midi channel?

Well it seem to work to change channel, but i guess to make sense one would have to pair each channel with a selected program. So i think i create those pairs at initiation.
So each channel hold a specific program right at start.

Evidently note off is diffent for each channel just as note on, well it simply has to be that way. So the final code to change midichannel must create two messages one for note on and one for note off.

function changeMidiChannel(){
console.log("Change MIDI channel");
channelC=document.getElementById("out_channel").selectedIndex+1;
console.log("channel ",channelC);
if (channelC==1) {mymessage=0xC0}
else if (channelC==1) {mymessage=0x90; mymessage2=0x80;}
else if (channelC==2) {mymessage=0x91; mymessage2=0x81;}
else if (channelC==3) {mymessage=0x92;mymessage2=0x82;}
else if (channelC==4) {mymessage=0x93;mymessage2=0x83;}
else if (channelC==5) {mymessage=0x94;mymessage2=0x84;}
else if (channelC==6) {mymessage=0x95;mymessage2=0x85;}
else if (channelC==7) {mymessage=0x96;mymessage2=0x86;}
else if (channelC==8) {mymessage=0x97;mymessage2=0x87;}
else if (channelC==9) {mymessage=0x98;mymessage2=0x88;}

else if (channelC==15) {mymessage=0xA4;mymessage2=0x8E;}
else if (channelC==16) {mymessage=0xA5;mymessage2=0x8F;}
output = mid.outputs.get(outportindex);
console.log("Channel ",mymessage," program ",programC);

Since my approach basicly forge the midi message, "my keyboard still send on channel 1" and i replace it. That mean that when i select program it always will change the program using midichannel 1. All the other channels do not care about that program message.

So "what message" actually change so the module listen/responce to another channel when i set the program? 

To be able to send a note to a channel doesn't mean that it will listen to a program change? The forging of note on and off "at the channels" seems to work good and not cause any latency.

But it would be nice to be able to change program at all channels, not only using midi channel 1.

Oops i had hardcoded the channel now it works.

function changeProgram(){
console.log("Change program");
sysexC=192+channelC-1;
programC=document.getElementById("prog_sel").value
output = mid.outputs.get(outportindex);
var programChange = [sysexC,programC];
output.send(programChange );  
}
