SetPitchBend not working?

[cz-chrome]

Hello,

I am having some trouble with the setPitchBend command. It throws an error "Uncaught TypeError: MidiOut2.channels[1].setPitchBend is not a function ". If I replace setPitchBend with something else it works as expected, so it appears to be specific for this command.

this is the code that gives the error:

PitchSlider.oninput = function() {
output.innerHTML = this.value;
MidiOut2.channels[1].setPitchBend(this.value);
}

If I replace it with:

PitchSlider.oninput = function() {
output.innerHTML = this.value;
MidiOut2.channels[1].playNote((this.value), {duration: 100});
}

Then there is no error and a MIDI note is sent upon adjusting the slider. So I can't figure out what I'm doing wrong. Any help would be much appreciated, thanks in advance!

TLDR:
Try sendPitchBend() instead of setPitchBend().

Full explanation:
The function name used to be setPitchBend() but all outbound function names have been standardized to use the "send" prefix in v3. For backwards compatibility, setPitchBend() still works on the Output object. However, since the OutputChannel object did not exist before v3, it only supports sendPitchBend().

That solved it, thank you very much for your quick response and for your fantastic work with webmidi.js!!

I got my original code from the example in your docs (https://webmidijs.org/docs/getting-started/basics#set-pitch-bend-value) so you might want to update that info.

And if I might make another suggestion regarding documentation: it took me a few hours to figure out how to send a control change. It turned out to be as easy as can be (.sendControlChange([cc number], [value])), but I had some difficulties finding out from the documentation. As I expect this should be a very common usecase for webmidi.js, it would be great if you could include it in the 'basics' section with a short code example.

Thanks again!

Cheers,
