And a (Linux) player I sometimes find handy is just a command line.

First off, let’s see what I’ve got available:

jon@worthy:~> pmidi -l
   Port     Client name                     Port name                                                                                                             
   14:0     Midi Through                    Midi Through Port-0                                                                                                   
   16:0     UM-2                            UM-2 MIDI 1
   16:1     UM-2                            UM-2 MIDI 2

At the moment, MIDI 1 on the UM2 is connected to the keyboard. MIDI 2 isn’t connected to anything but could wind up as a module from ebay…

So to play midi file to keyboard:

jon@worthy:~> pmidi -p 16:0 my.midi
