Check everything under "Filters" tab (it is the default setting). Take a look to the "Display" tab, too. 2. Use Connections->Connect All, or Connections->Configure Connections and check everything in "Available ports". You should see some "ALSA Port Subscribed" messages. Now, you should see MIDI messages in realtime while you are pressing keys. To check if there is something wrong with ALSA sequencer, try also "vkeybd" (a software virtual keyboard). Use the Connections menu in KMidimon after starting the vkeybd program. Regards, Pedro
