Disabling channels/instruments

[Ep8Script]

It would be great if it were possible to disable specific channels or instruments with this library (or libopenmpt), but there doesn't seem to be a way to do it. I've tried a lot of things (including reading up on some information here), but I've unfortunately been unable to get it to work.

Is there something I'm missing, or is this not doable here? Thanks!

I'm sure it can be done. libopenmpt can supports muting channels using the set_channel_mute_status function. However, I can't figure out how to call openmpt_module_ext_get_interface from JS correctly to obtain the mod_ext pointer. I'll experiment later today if there is time.

[Ep8Script]

Yeah that's where I got stuck unfortunately. Appreciate you taking the time anyway, good luck and thanks for creating this project!

I'm investigating this too. Doesn't look like set_channel_mute_status has made it into the libopenmpt.js conversion.

I did a bit of research and I think we might have to create some bindings so we can access the openmpt_module_ext_interface_interactive struct from JS and call the functions pointers there using Emscripten's dynCall. Not sure whether it'll work though.

@deskjet i prefer to use wasmTable.get(functionPointer) because i can apply argument more flexible.
