I think any flags sent are ignored. There are flags set internally when Csound is instantiated to make sure it has a ksmps value compatible with the Web Audio API callback. The Csound javascript API does support midi input though so if you wanted it to play a MIDI file you could send MIDI data to the Csound instance.

I think we should look at the code again to make ksmps independent of the web audio buffering. From a global
perspective, I cannot see that being impossible.

Yes, it would be better if it was flexible in this respect. I will add an issue to github. 

Rory, I've just checked and although there is a way to send MIDI data via a connected MIDI device, there is currently no way to send MIDI messages to Csound directly in the public API, I thought there was so apologies if I gave that impression. The only way I can think of to play a MIDI file would be to set up a MIDI loopback, play the MIDI file from one program, send it to the loopback device and get the browser to receive through that loopback device. That sounds like major hassle though. But if you were up for it, enabling MIDI input to the browser is done like this:

var midiInputCallback = function(status) {

if (status === true) {

// We have successfully enabled midi

}

else {

// Error midi was not successfully enabled

}

};

csound.enableMidiInput(midiInputCallback);

Midi is then received from the first connected MIDI device.

Thanks Ed, I was afraid of that. Adding compile flags seems like it should be simple enough? If I wanted to add features, how would I go about doing it? How is this Csound js interface even built? I can't find any info on it. There seems to be no documentation on what's available or possible, or how to build it? Any ideas?

There are instructions to build here https://github.com/csound/csound/tree/develop/emscripten, the source is there as well, you want to look at CsoundObj.c and CsoundObj.js. They are pretty simple files where the C file wraps the Csound C API for use with Emscripten and the Javascript file just wraps the compiled C code into a Javascript object. There is also a list of methods with descriptions in the Floss manual.
