 #
-#   $ sudo modprobe snd-aloop
-#   $ timidity -Os -o "hw:Loopback,0,0" -iA --sequencer-ports 1
+#   $ xset -r && vkeybd; xset r on

-# then connect to Timidity++ with a MIDI input device, e.g.:
+# Find out the port of the input MIDI device:
 #
-#   $ xset -r
-#   $ vkeybd --device alsa --addr 129:0
-#   $ xset r on
