-    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.
