Home Page Forums MAME Non-Windows MAME Support Can MAME in browsers support external midi device?

Hello,

Recently I was attempting to run many electronic keyboard emulations in the browser, using MAME compiled by emscripten. Currently, I've managed to run the emulator and play the MIDI file via the `-midiin` parameter, but haven't figured out a way to make the emulator controllable using an external MIDI device like MIDI keyboards and sound modules.

I know that modern browsers support web midi but I didn't find much information for connecting the web midi to an wasm application on the web page. Is there a solution to achieve that?

We don't have a driver for Web MIDI in Emscripten builds and as far as I know PortMIDI doesn't support it yet.

Thank you R. Belmont. I guess it might take a while till the midi function is fully implemented.

By the way, I saw an example on this page https://forum.pdpatchrepo.info/topic/13746/webmidi-and-emscripten which takes the web midi note events and forwards it to the wasm application. It is still limited but I guess maybe it can be a workaround.
