qmidiroute  is  a  versatile  MIDI  event  processor  and  router  for the ALSA sequencer.  The graphical
       interface is based on the Qt4 toolkit.  qmidiroute permits setting up an unlimited number of MIDI maps in
       which incoming events are selected, modified or even changed in type before being directed to a dedicated
       ALSA output port. The maps work in parallel, and they are organized in tabs. With qmidiroute  it  is  for
       example  possible to change or invert the scale of a keyboard, to transform keyboard strokes into program
       changes or controller data into notes.

       Incoming MIDI events can be logged in a list and are displayed in different  colors  according  to  their
       MIDI  type.   qmidiroute provides one ALSA input port and as default two ALSA output ports. The numerical
       ALSA client id is displayed as part of the window title.

   GeneralUsage
       After starting the application, the Unmatched tab is presented (see below). To start MIDI routing  setup,
       the  Newmap...   button  can be clicked, which will create a new MIDI map appearing as a tab in the map
       area. The entire setup can be saved to and loaded from a QMidiRoute file  (.qmr).  Several  maps  can  be
       created  to  work  in parallel. The maps can be organized using the MapRename,Remove and Clone buttons.
       The EventLog is displayed in the bottom area by default, but can be hidden if not needed or floated as a
       top-level window on the desktop. Logging can also be disabled generally or for MIDI Clock events only.

   MIDIInput
       The Input field represents the incoming event  filter  of  each  map.   Handled  event  types  are  Note,Controller,Pitchbend  and  ProgramChange.  The events can be filtered by their respective values or by
       MIDI channel. Events matching the conditions specified in the Input field  are  directed  to  the  Output
       field.

   MIDIOutput
       The  Output field sets terms into which event type the matching events are transformed, how their channel
       and values are transformed, and to which ALSA port they are directed.  Channels and  Values  can  be  set
       Fixed,Offset or ReverseOffset with respect to the input event. As an example, ReverseOffset will take
       the value specified and subtract the incoming event value from it to produce the output event  value.  If
       the  output  range  for a value is different from its input counterpart, the input range will be smoothly
       scaled to the output range. Events will be sent to the ALSA port specified. The number of available  ALSA
       ports can be set using the corresponding command-line option.UnmatchedMIDIevents
       In  the  Unmatched  tab,  the  handling  of  events  not matching any input filter of the defined maps is
       specified. These events can be discarded or sent to a specified ALSA port.

       An example MIDI map file can be found in /usr/share/qmidiroute or in /usr/local/share/qmidiroute
