Is it possible say to PD to lauch alsamidi in a patch.
I mean in the same way as:
[loadbang] ---> [;
dsp 1]

Thanks for your answer.

You can do it with the [mediasettings/midisettings] object.

Also, if you want Pd to load by default, go into the Preferences and add -alsamidi to the startup flags.

Thank you Maelstorm,
It works
